John,
Ok…the PC is sending you the ESC sequence rather than you sending
it to the PC…and the ESC itself appears to be getting dropped, but only
at 2400 baud…right?
That sounds like a problem in your serial board, not in the Amiga.
The Amiga merely takes what your program puts into the BridgeBoard's video
RAM area and displays it. Your program is what controls what is in the
video RAM area. It (your program) does all translations, cursor control
and so forth. Since it's not getting the ESC character, as you've noted,
it is not translating the rest of the sequence into cursor control, so it
shows up as plain text.
The only way your program wouldn't get the ESC is:
a. It's not being sent (unlikely)
b. The modem is "eating" it (also unlikely)
c. The serial card is "eating" it (likely)
If the BB was too slow to read data from the serial card, it would
cause the serial card's buffer to overflow (or an XOFF to be sent) but
you'd drop random characters…not just ESC characters.
Is it possible for you to try another serial card?
Don
