Posted 15 Jan 2009 Hello everyone, i have to do some work with a basic card that is sending information back and forth from a technifor printer. I understand the best way is to use hyperterminal which i have. Has anyone ever used it? and how do i get on line with it and how do i get the information off of it so i can modify it. Then what steps do i ahve to do to put the information back on the basic card? Thanks in advance for all your help. Mike Share this post Link to post Share on other sites
Posted 15 Jan 2009 There are three popular A-B BASIC cards; 1771-BAS Series A, 1771-BAS Series B, and 1747-BAS. Each work a little differently, but the essence is that the terminal program (usually Hyperterminal) acts as, well, a terminal. You give it commands like "list" and "run" and send it control characters like control-C and it reacts to them. The first thing you need to do to back up or modify a BASIC program is get a listing of the program. Then you can modify it, clear the module, and load the program back in. First post the type of module you have, and find a User Manual for it on the RA Literature website. Share this post Link to post Share on other sites

Posted 16 Jan 2009 you may want to try connecting two serial ports of your pc (or two pcs) to test hyperterminal. few general things to know: - pick right cable (straight or crossover, for PC to PC it's crossover such as 1746-CP3). - if your cable has only TX,RX and GND connection, don't use hardware handshaking - both devices must use same port settings - make sure you know which port you use - don't always trust hyper terminal, have another program that can show each character in hex (like Serial Monitor in download section) etc. Share this post Link to post Share on other sites
