DOS Serial I/O

Comment:

IS it possible to open the COM1 serial port and read/write from/to it using batch commands in DOS 5.0? If so, how?

Try researching the "MODE" command. I vaguely recall someone communicating with their modem in this fashion. :) - W0rm

I havent got a clue, but it would come in handy if it was possible.

Yes you can. Use MODE to set the port configuration so the 2 devices match each other. eg: MODE COM1:2400,N,8,1,P Then use COPY to copy a file to the port or to copy the port to a filename. COPY FILENAME.EXT COM1: or: COPY COM1: FILENAME.EXT

Also, if you just want to send data out to the port, like if you want to reset your modem, use piping to redirect text, like this: echo atz>com1:
