If the device's DB-25 connector is a parallel interface and not a serial one,
then you're out of luck. You can't plug it into the PC's serial interface,
but MS-DOS Kermit does not support the parallel port as a communications
device. Parallel and serial interfaces are entirely different; no amount of
rewiring can make one communicate with the other.
Have you ever seen the output from this device under any circumstances?
If so, what were the circumstances?
