(sorry about posting under wrong subject, my news reader)
Hi, this isn't strictly a djgpp question, but I was hoping someone here 
would know this. I need to boot DOS via serial port (to debug the 
graphics). It works with mode "COM1: 96,n,8,1" and "ctty com1", but only 
if hardware handshaking (RTS/CTS & DTR/DTS) are connected. 
Unfortunately, on the system I need to debug these signals are not 
available. I understand Windows versions of the MODE command support 
rts, etc arguments, but legacy DOS (v3.21) does not.

So the question is, does anyone know of a way around this - a patched 
MODE version, for example? Or how to poke the serial port to not use RTS 
/ DTS after mode command?

Thanks,
Ivor
