The programs you transfer might also contain comments which are part of the STRING that gets transferred. For one thing, the programs probably need to be in a binary mode for transfer.

First store the following small program on the 49g+ (or 49G). Note that the entry point is different for a 48 series, so don't use it there. And note that misuse of SYSEVAL can have dire consequences. I'm using the Kermit backslash translations here. I call it 'KINVIS49'to distinguish it from the version for the 48. @ Checksum: # 61C0h @ Bytes: 20. << ->STR @ Make sure there's something on level @ one, and convert it to a string if @ it's not already. # 2F34Dh SYSEVAL @ KINVIS for 49G/49g+ >> If the object is intended to be a string (or contain a string) that for some odd reason you intentionally have NUL characters in, then edit them to 000 before downloading the file. Similarly, if for some reason you have a CRLF pair that you *don't* want translated to just LF, either translate the CR to 013, or the LF to 010, or both. Download the object via Xmodem. (I haven't mastered this step yet with the 49g+.) Recall the string to the stack. If the object is intended to be a character string, be aware that Xmodem probably padded it with NUL characters at the end. To get rid of them, do 0 CHR SREPL. If the object is to be something other than a string, then this isn't necessary as the compiler will treat any NUL (except within a string) as a separator, and therefore discard it if it's at the end. Oh, you used an SD card, so the above shouldn't apply. Probably a lot easier than using Conn4x. Now do n TRANSIO, where n is the T parameter in the header. That is, for your header, %%HP: T(2)A(R)F(.);, use 2 TRANSIO. This sets the translation mode to match the file. Come to think of it, it shouldn't hurt to use 3 TRANSIO regardless of what the translation mode of the file is. Make sure that your Angular units (Radians, Degrees, or Grads) on the calculator matches the A parameter, and that your Fraction mark on the calculator matches the F parameter. Now run the KINVIS49 program on the string. This will translate the backslash codes back to the corresponding characters, respecting the translation mode in IOPAR. There should be an empty string on level 1, which you should drop; just keep the level 2 string. Now do 20 OVER SIZE SUB to get rid of the header. If the object is intended to be something other than a string, do STR-> (or OBJ->) to compile it. Store it as whichever variable you want. I have confirmed that the entry points for KVISLF, KINVIS, and KVIS are the same on the 49g+ as on the 49G, and that they do the Kermit backslash translations just fine, so the above should work. But I still haven't gotten Conn4x to connect yet, so I won't claim that it's entirely tested. -- James ==== The 49g+ at last arrived on my desk... But I don't have any Windows on my laptop, only linux. Did anybody managed to connect linux & 49g+ ? I tried doing insmod usbserial vendor=0x3f0 product=0x121 to force the use of the serial driver, but it doesn't work that well: echo bla > /dev/ttyUSB0 only makes the hp get bla, not n. The other way doesn't work at all: linux doesn't receive anything (debug=1 doesn't say anything) (BTW, this is 2.6.0-test7, I haven't tried 2.4) Samuel Thibault ==== > The trick is simply to press and hold the ON key during the display > earthquake. After a few seconds, release the ON key. Very ingenious, but still not very easy. You have only about .25 seconds to press the ON key. RaM. ==== I think that I've read all of the previous posts about Conn4x problems, but I still haven't gotten it to work. I guess that I must be stupid. This is on MS-Windows 98SE. The 49g+ ROM is at revision 1.22, the Conn4x.exe at 2.1.0.1783, and the USB driver at 1.0.4.2. First I installed the USB drivers and Conn4x as downloaded, but Conn4x wouldn't work. Ok, so I removed what I had installed, and installed the packages from the CD-ROM. Still no go. Now I've installed the downloaded packages as updates. No joy. In device manager, I see the HPx9G+ DEVICE come and go as I turn the calculator on and off. Properties shows me The device is working properly. Yeah, sure. I have flag -33 clear (Transfer via wire). IOPAR is { 115200. 0. 0. 0. 3. 3. }. The display shows Xmodem Server Waiting for command. Running Conn4x, whether I use Connect using Auto or choose HPx9G+ from the drop-down list, when I do the File Connect... OK, I get the silly flashlight with the Looking for calculator message, and occasionally an Error (No device connected. Check the cable connections and the calculator.) message comes up. More often it just keeps looking until I try to shut it down, and in those cases, shutting it down requires a Ctrl-Alt-Delete, and Close Program shows me Conn4x (Not responding). About half the time, End Task will work ok, but the rest of the time it just gets me to the Blue Screen of Death, from which even another Ctrl-Alt-Delete won't do anything; it needs the reset button, run Disk Doctor and all that hassle. If I try the File Capture Calculator Screen..., I get the box explaining how to use it, but pressing ON-CursorUp on the 49g+ turns on the transfer annunciator without Conn4x responding at all. I was trying to go through my USB hub. I decided to connect directly to the PC's USB port instead, but it didn't make any difference. I had updated the ROM using an SD card, but decided to try it from Conn4x just for the heck of it. It actually worked! But nothing else about Conn4x is useful to me. To be sure, I can use the SD card and reader to move things to and from the PC, but it's beginning to annoy me that I haven't been to get Conn4x working. Does anyone have any idea what I'm doing wrong? I mean other than using a Microsoft product with an application and device that perhaps isn't quite ready for release. -- James ==== This might be overstating something obvious but I had the same problem because I was using the wrong keys. I used the (9.1)RedShift key released it and then the (10.2) Red right arrow. Of course that was wrong, and of course it didn't work. That was what the instructions seemed to imply to me at the time, though. So then I tried Xmodem via the IO function under Apps thinking that should do it ... but no, it didn' either. Then some kind sole set me straight: Use the RedShft key (9.1) with the Chrome Right Arrow I guess you could call them the scroll keys. Damn, that did the trick(!) and I felt pretty stupid for not figuring that out myself! downloaded dir's and vars on the hp49g+ with a 250MB SD installed using Conn4x successfully. Even the 250 MB SD seems to be compatible with the hp49g+ so maybe I can pass that help along for your use or others, and my stupidity will have some value after all! -Dale- >I think that I've read all of the previous posts about Conn4x problems, >but I still haven't gotten it to work.

The documentation is poorly written; when I see Right Arrow, I quite naturally think of the right arrow, that is, the one on the right-shifted 0 key. They should've written Cursor Right to make it clear. But I had the benefit of previous experience on the 49G, familiar Xmodem server. > downloaded dir's and vars on the hp49g+ with a 250MB SD installed > using Conn4x successfully.

What Windows(TM) did you use? 98? ==== WinXPpro w/Conn4x. I need to admit that I just received the hp49g+ and have very little time to scale the learning curve. I am a long time hp48sx user, and much of the skillset from that experience is useful on the new calc. The one thing that seems noticable to me at this early point, though, is my lack of efficiency with this machine. I have to spend too much time for such little productivity. The good news is that none of the problems read about in this newsgroup have been noticable yet. I was able to update to rom ver. 1.22 shortly after discovering the way to get Conn4x to see the hp49g+, so I have no experience with whatever the earlier rom version was. >> This might be overstating something obvious but I had the same problem >> because I was using the wrong keys.

Tom, if I thought that MS-Windows 98SE didn't handle USB ports properly, then I wouldn't find fault with HP over this. But consider that 98SE handles every other USB device that I've ever tried with it without any problem, and that Conn4x with the 49g+ is the only one that doesn't work. Also consider that Conn4x doesn't work with my 49G on the COM port, although the 49G works just fine with the older Xmodem ConnectivityKit, HyperTerminal, and usually with the Kermit HPcomm application. Is it such as a surprise that I suspect that either I'm doing something wrong or else there's something wrong with Conn4x? And yes, I realize that many new PCs lack other means of connecting devices, so adding USB is certainly a good thing. I've been wishing for it since I noticed the 49G and realized that HP had resumed the development of advanced calculators. But I can still wish that they'd managed to also keep an RS-232 port, because for many things it has huge advantages over USB. I don't know just where they'd put another port, but it needs only 4 pins, and could use a miniaturized connector; it doesn't have to be as big as the 48 series or 49G RS-232 ports. -- James ==== > >>No, if I can't get Conn4x working, I'll just choose to do all transfers > >>with the SD card.

Come to think about it, all of the calculators that have communication capabilities, even the older models, could work with open source operating systems, as long as HP continues to allow us to have information on the internals, and if some experts were willing to work on it. -- James ==== James, I'm the last guy that should give you technical advice... on anything! But I'm thick, so here goes: I know USB is not native to Win98; but I am not sure about 98SE. I also had run into the proverbial brick wall trying to flash my 49G+'s ROM via Conn4x. But on this basis, I took the USB cable out of my high-speed USB 2.0 port (on a PCI card) and plugged it into the USB 1.0 port that came with my dinos..., uh, computer. But your USB ports the v. 1.0 ones. Try booting with the 49G+ on and connected. Then run Conn4x. Also, I suspect both versions of Win98 has problems with consistently recognizing USB plug'n'play connections. Even with using my older 1.0 ports, it works unfailingly only if I boot with my USB device already plugged in. Also, and forgive me if I insult you, but this got me- the 49G+ is factory set, I believe to connect at 115,200 baud, while Conn4x's default is 9600. I got it to work after I also made both 115,200. Oh, and, the correct port choice, is, 'natch, hpx9g+. Now, Conn4x can see my calculator! My problem was figuring out the 49G+'s syntax; I'm still not too sure I got it... oh, if you disconnect the USB link it sometimes generates the ol' blue screen of death. Getting this ROM upgrade took literally a minute and maybe a few seconds more, but getting to this point to about two or three hours. But I digress- to update the ROM, I just chose ROM from the Conn4x menu and it then asked for the update file. After choosing this file, Conn4x began the connection to the calculator. At that point, I had to do the hold + and - buttons together and RESET and release and unplug USB and replug USB thing, but that did the trick. VERSION tells me it's 1.22 (I forgot to do that before upgrading, though, so I can't say for sure what version it shipped with).

Well, I don't know about native, but it's included with 98SE. Probably crammed in amongst the rest of the hodge-podge that makes a Microsoft product would describe it better. But except for this, it's always seemed to work perfectly for me. > I > also had run into the proverbial brick wall trying to flash my 49G+'s > ROM via Conn4x.

This PC is almost new, only a few months over 3 years old. ;-) But I haven't found any reason to replace it. My other PC is a teenager now, it goes back to 1989, and still works just fine, but modern software requires a bit more, and adding so much to the old one didn't look cost-effective any more. Of course the older one lacks USB. > Try booting with the 49G+ on and connected. Then run Conn4x. Yes, that's what I tried first.

A printer, the USB hub, two different scanners, the USB/RS-232 converter, and now the SD card reader all work fine with plug'n'play. That the device manager has the HPx9G+ DEVICE come and go as I turn the calculator on and off suggests to me that plug'n'play is even working fine with the 49g+. > Also, and forgive me if I insult you, but this got me- the 49G+ is > factory set, I believe to connect at 115,200 baud, while Conn4x's > default is 9600.

I think I found them both set to 115200, but just for the heck of it I tried setting both and 9600. I'm not sure that Conn4x pays any attention to the speed setting when it uses the HPx9G+ port. Now they're both back to 115200. > Now, Conn4x can see my calculator!

Yeah, strangely enough, I don't have any problem at all getting it to do the ROM update. Except that holding down the two keys while sticking a paper clip into the reset hole is a bit clumsy. It wasn't this difficult with the 49G. But on the other hand, with the 49G I had a nice long break while it was downloading a new ROM; with this, I hardly have enough time to get another coffee. -- James ==== -=[ Sat, 25.10.03 6:39 p.m. +1300 (NZDT) ]=- [...] > Running Conn4x, whether I use Connect using Auto or > choose HPx9G+ from the drop-down list, when I do the > File Connect...

Just getting the HPx9G+ in the connection drop-down menu tells me that it should know that the 49g+ is out there. Being able to do the update proves to me that it can communicate. So why won't it connect -- James ==== -=[ Sat, 25.10.03 8:15 p.m. +1300 (NZDT) ]=- [...] > Yes.

So why won't it connect I don't know. All I can think of trying is unplugging and re-plugging cables to try and stimulate a connection. You know, the old fall back method - toggle as many things as you can, like when playing a so-called adventure game. Even stopping and restarting the Xmodem on the 49g+.

I like the form factor of the 41CV, the way it sets in your hand, and even the keyboard layout. But the 42S wins slightly because of it's base conversions. I do a lot of embedded microprocessor work, and when it comes to computer math the 16C is absolutely the best calculator ever made! I bought mine new and if I had known they were going to be discontinued I would have bought 10 more, one for every desk I might ever have, and a backup for each of the ones in use... I've never found an simulator/emulator that's as easy to use, or does all the different integer maths properly (I have yet to find one that does one's compliment, not to mention setting the carry and overflow flags properly!). Not that I've looked that hard, since I do own one. It's funny, but every 16C I've seen (which admittedly is not that many) uses painted over keys. If you look at them sideways and let the light reflect off them you can see their original stampings. My calculator started as a scientific calculator, it had to have been an 11C or 15C, since the GSB key has been printed over a SST, and the 10C had that as it '%'. They must not have made very many of them and it doesn't look like they ever really committed to making many these. If there were only a 12C to 16C conversion... ;-) Now if there were only a decent 16C simulator (switching between bases without having to press a shift key, proper displaying of the carry flags, ability to set the bitsize when using integer math, etc.) running on the 49g+, now *that* would get me to buy a 49g+! Someday I'm just going to have to find a calculator that I can program in it's native processors mode, that gives me enough control of the keyboard and display, and recreate this masterpiece of a calculator! If I had the ability to mold plastic I'd recreate this calculator's style and layout, stick in a small modern processor, and rewrite the firmware myself.

That's exactly how I feel!

Your message prompted me to look mine over very carefully with a strong light and a magnifying glass. All the keys appear to be injection-molded; I can find no evidence of them being painted over.

As you note below, the other ports can take the libraries; do we really need port 3 for libraries? That way it only has to scan the root directory, and scan subdirectories as they're opened. >>have at most 512 entries in the root directory with standard formats. >> >>And I expect that very likely most of the files wouldn't be libraries. > > Quite right, libraries can fit into the Flash (port 2) > > >>I wonder how long FILER would take to do the same thing. > > Really long going through every subdirectory to check the files types > to match that of a HP library - it's slow even now!

I've been using SN 33402524 since Wednesday and can make the same observation. At this point the keyboard feels fine, with no obvious signs of intermittency, although keypresses do seem a bit loud. I did the firmware upgrade shortly after powering it up for the first time, so I don't know how much of a firmware component there might be to the problems reported. It's so much better than either of my 49's that I'm not about to complain, but it also doesn't inspire me to dispose of my 48's (S/SX/G/G+/GX), and it can at best supplement my 16C. - rfb ==== Hope its ok to post again about this.

I have a USB/RS-232 converter that I use with the 48 series and 49G, but that's with the USB side connected to the host (my PC), and the RS-232 side connected to the device (or client to put it another way), the calculator. It works except that it won't handle a screen capture to HPcomm through the converter, although screen capture works fine with the built-in serial port. Note that my converter requires a driver on the PC. I have my doubts about finding a converter that connects to the device on the USB side and the host on the RS-232 side, but who knows? Also note that the 49g+ is supposed to be able to communicate via IrDA, and I would hope that you could use Kermit with IrDA. I wouldn't think that it would be too terribly expensive to add IrDA to a PC, and I know that there are IrDA/RS-232 converters available. Maybe someone who already has an IrDA port on his PC could test whether it works with Kermit and let us know. -- James ==== > I have a USB/RS-232 converter that I use with the 48 series and 49G, but > that's with the USB side connected to the host (my PC), and the RS-232 > side connected to the device (or client to put it another way), the > calculator.

The classic MINEHUNT game was ported to the HP49 by D. Lidstr.9am. I used parts of it to reprogram the game which now runs perfectly on both, the 49 and the 49+. It is called MINES and is half as big as the original MINEHUNT (only 1.9 KB) but has twice as much comfort. The main problem in the 48 MINEHUNT was spontaneous garbage collection. This problem has been fixed in MINES which also has a separate command number of mines. Playing with 50 mines in an open area is an exciting labyrinth game not only for children (finding the shortest way to the right lower corner if there is any). Suspension of the game with STO does not create anymore this ugly LIBDAT, and also no extra-variable NMines for storing the number of mines. These data are hidden as it should be. MINEHUNT's main messages YOU MADE IT!! and YOU BLEW UP!! have not been translated into French although they still live in the internal library 231 all messages of which concern MINEHUNT. Translations of these messages are seemingly too long for the header. These messages had to be escorted with corresponding sounds. Serious problems with the 49+ beeper were the reason for updating MINES. With some fast played low frequences the HP49+ becomes awful slow. (By the way, all CAS messages had been translated into French. An awful task because some of these messages are very long :-) Run 222 LstM (a command from my library Msgman) in French. - Wolfgang http://page.mi.fu-berlin.de/~raut/WR49/index.htm#Games ==== I know all you folks have a lot of other things to worry about, with the 49G+,what the connectivity program not working,missed key presses, etc. Several days ago I saw a list of pros and cons about the 49G+ and one was that it did not have a slide on cover like the 49. I have temporarily solved this problem for folks in the U.S. ( Maybe other places too), that got their G+ in a blister pack. Just cut the bubble covering the calculator out of the blister pack and put it over the calculator before you slide it into the leather case. (Use a nail file to smmoth out the rough edges) It also keeps the keys from rubbing on the top seam of the case when you pull it out. ==== I already used up mine for the 48G (now used by the 48G+). I took the added precaution of gluing a stiff piece of plastic over the screen area of the bubble packaging cutout, as the original 48G cases are a bit on the soft side. I'd really recommend this as years ago, I saw too many reports of guys wrecking their 48G's simply by dinging the screen area, even while in its case. But I got my son the recently discontinued HP-39G and HE does not want the packaging, of course, so it's still on my desk. It's almost a perfect fit for either 48G+ or 49G+. But the material of this new 49G+ case is quite a bit stiffer than that of the 48G, so I suppose just the bubble package cutout is enough. Oh, and good advice- filing the edges! > I know all you folks have a lot of other things to worry about, with > the 49G+,what the connectivity program not working,missed key presses, > etc. > Several days ago I saw a list of pros and cons about the 49G+ and one > was that it did not have a slide on cover like the 49. > I have temporarily solved this problem for folks in the U.S. ( Maybe > other places too), that got their G+ in a blister pack. > Just cut the bubble covering the calculator out of the blister pack > and put it over the calculator before you slide it into the leather > case.
