Serial communications question

[Mark Bresler]

I used to communicate with my new micros boards using Apple Macintosh computers running system 7.5.5 and the Red Ryder 10.3 communications program. Baud rate was sent to 9600, and I set the program to wait two seconds after each line was sent. This was because Red Ryder could not be set to wait for a control J character(as requested by the instruction manual). This worked fine across many computers and many new micros boards. Due to space limitations in my office, I am trying to use a Dell computer (3 GHz, 0.5 Gbyte running windows XP to host MITterm version 0.9.85. The terminal program displays the power on message, will print out all WORDs when asked, and will dump memory when requested. I get download errors and freeze up when I try to load the program. I have tried Xon/ Xoff, and 2000 msec line delay. I am connecting transmit, recieve, and ground wires between the computer and SBC, no hardware handshaking is used

I seem to remember a Forum question about this some time ago, but cannot find it.
Any help would be appreciated
Thanks,
Mark

If you're using NMITerm, this ought to be easy. You can set for line end echo as was suggested but the Mac wouldn't do. In NMITerm properties, in ASCII settings, chose line pacing with a 10 (DEC) or A (HEX) setting. Now some USB to serials also need the character pacing set. That really should do it.

You don't want XON/XOFF, because the boards don't recognize or know what to do with the ^S ^Q characters. You can do the long delay and that should still work too. But it makes for a very long download.
