Amen to the XON/XOFF problem.  PC-DOS provides NO built-in XON/XOFF support.
I would very much like to have an installable device driver for PC-DOS that
allowed a C program to open COM1 or COM2 just like any other device, but
no one seems to build one.

For someone experienced in building PC-DOS installable device drivers,
this should be a pretty trivial problem.  We are building a product right
now for PC-DOS machines that could use such a driver -- but we can't find
such a driver available for sale.

Please.  Someone build this thing, and make my life easier, and you a little
wealthier.  If you know of such a product, please contact me.
