Post by thread:[OT]sort-of Re: Rs232 Monitor Programs and port se

Recently, in my work with a local charity, I got access to an old eprom programmer aimed at the 2700 series chips. Since I have literally hundreds of these in storage, it seemed the right choice, to see if I could get it working... Alas, although, it seems to do its internal workings correctly, I can't seem to talk to it..... The circuit is the SPR 2700 ELEPHANT EPROM PROGRAMMER which was made locally, and there is an indication that it was made by Pembina Automation, which might or might not be a subsidiary of Pyramid electronics. (I also heard it might be a subsidiary of Sherrex electronics, which is either a sister company, or a competitor, to pyramid according to their www pages.) In any case, while it will program an eprom, and test to see if it is valid for any of the 12v Eproms, it doesn't seem to want to talk to my PC. Ideally, I would like some sort of software that would alow me to sense the nature of the communications it is trying to send, so I can reciprocate and read the data, or the actual original driver/software so that I can read/write to it. I get the feeling that the circuit is not presently being supported by its parent company.... which is not surprising at all, little that gets trashed, is. So if anyone is familiar with this circuit, or knows someone who used to work with it, and might have the software to drive it, please let me know. I figure it is the minimal system I need, to be able to impliment a parrallel version of my greylogic device for evaluation. Having a number of old 27XXX devices, I would like to experiment with them before getting more expensive devices such as flash eproms.

Unfortunately, I had to pick one to use, and the best so far in terms of watching what is going on with minimum hardware, learning curve, etc. is COMLITE32 from <http://www.rtcomm.com>. Free, runs under windows, and monitors port activity on the same computer--so you can be running your application code, and watching the data going in and out of one or two comm ports on the same machine, in hex. Many of the others ran a very close second, but this one gets my vote. Caveat: It is a beta release, but seems to work fine--so far. kelly William K.

Kelly, I recall you saying the a PC won't handle 115200 well. I'm using it in my current app between a PC running DOS (I wrote the ISR) and a Win95 230 MHz laptop. No problems.

Andy: Actually, I've got it running too--between to Win98 systems running 133 and 200 MHz. Was remembering an old system (286-33 mHz days) running DOS. Had to do a custom ISR for that as well. Was for downloading real time heart sounds from an electronic stethoscope from the Space station/shuttles. VERY interesting project ten years ago. K.

My DOS machine is a 486SX/100. The ISR isn't anything fancy - it's all in C.

Borland Speed Bug? I am using a 486dx66 from Compaq and an actual IBM 350-P133 would the speed bug be in my computer, or in the software I am using to read the port? I tried both procomm for windows, and an early datamon evaluator with no success. I have a freind that claims to have developed a frequency counter for his C64, would it make it easier to figure out if I could sense the Baud Rate?

The bug is in the DOS Borland compilers, when used on a very fast machine (400MHz PII upwards?) the counter used in the delay() procedure initialization overflows to more than 16 bits. This would be fine, as the register used is 32 bits wide, but the routine copies the resulting value to a 16 bit register - this causes the 'error 200', which actually means 'divide by zero error'. Your two machines are much too slow to have the problem, AFAIK it only happens with Pentium II and III machines, and not on the slower Pentium II machines either. There is a patch available for programs written using Turbo Pascal 7, it's available from my website, I presume there are similar patches available for use with Turbo C programs?. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : RemoveMEnigelgspam_OUTKILLspamlpilsley.demon.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.demon.co.uk | | Chesterfield | Official site for Shin Ki and New Spirit | | England | Ju Jitsu | \--------------------------------------------------------------/
