Hi Everyone,

There is the SetupComm() function which allows you to request buffer sizes,
although it can be ignored by the driver..

mmun_29il.asp

I'd suggest that the original poster not try to do this, but rather sends a
single byte and waits for a response from the PIC before sending the next..
Doing this at a higher level then the PC UART will make is more likely to be
portable, but it will make it slower.

Cheers,
Ash
