One of the deficiencies of PC-DOS is that it does not support COM1 and COM2
(the RS-232C ports) in a manner consistent with the rest of the devices on
the system.  You can't redirect stdout or stdin to a serial port and have
it work.

Our requirements are for a installable device driver for the serial ports
that use XON/XOFF and appear like any other device to PC-DOS.  Do you know
of one in the public domain, or does anyone have any experience with any
of the commercially produced device drivers?  (For example, the driver
sold by TextSet.)

Right now we are using the Blaise Computing serial I/O package.  It works,
but it is nowhere near as convenient to use as a standard PC-DOS device
driver, and I'm spend far too much time figuring out why one minor little
change HERE causes it to stop reading characters THERE.
