I had some trouble with it as well.  Ultimately, one fallback to
consider (but slower) is to echo characters back to the PC and if the
PC detects that line wasn't received correctly, it sends CTRL-X and re-
sends the line again.  This is especially useful if using a higher
baud rate like 9600.  As for setting baud rate, you can do it with
pokes from basic, I think, but the CTRL-A stuff only works from the
basic prompt bc. of how the rom firmware latches itself.

If you look here, you can see how I disable IRQ and //c keyboard
buffer routines that interfere with higher-speed transfers:
