Note that mac serial ports don't have an RTS pin, so crtscts doesn't
necessarily do what you want. Also, figure out the pinouts of how your mac
-> DB-25 cable works. I've had different ones connect the mac pins to
different DB-25 pins.

I'm glad to see the cable works hooked up to a different box. Maybe
something was wrong with the serial port.

If the mac <-> DB-25 cable is wired right, you can use cdtrcts flow
control on the mac which will correspond to crtscts on the PC.

Take care,
