Hello everyone, I hope some of you guys could help me out? I've got a CNC milling machine hooked up to an old (Pentium 166) PC running Win98 via the
9-pin serial port (com1). It works fine, but no matter what settings I change, I can't get it to work on com2, and more importantly, when I try to get it to run on a brand new PC (which it will have to do, as we want to get rid of the old one) it doen't work properly. On the new PC, it only seems to want to RECEIVE data from the machine, but when I try to TRANSMIT data to the machine, it does nothing. When I tried cables with the Rx and Tx swapped around, it didn't even want to receive data. I've tried it on two other new PC's runing XP with the same results. There are no conflicts and no serial mice/modems etc.Any help you guys can offer would be such a great help!
Thanks,
-Tone.
