Dear Arkady and collegues,
There are so called "controller-less" hardware modems, both
ISA and PCI, which are some intermediaries between "win" and
"usual hardware modems". (I have, for example, Intel (R) 536EP
modem). They, partially, emulate COM ports. For many of them
there are drivers under Linux and FreeBSD.
Does anybody know at least one example of DOS driver
for such almost "normal" modem?
Are there any PRINCIPAL barriers in DOS architecture, to
develope such drivers, apart it's not easy?
