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?
