[comp.dcom.modems] MNP in Software?

jcs@tarkus.UUCP (John C. Sucilla) (01/31/88)

I've seen a lot of talk going down on MNP error correcting modems and
started wondering if there any UNIX communication programs that can emulate
an MNP modem. I could handle the delays if the noise would just go away...

There are PC comm programs that emulate MNP level 2. A number of comm hackers
I chat with have discussed creating such a facility for UNIX, possibly as a
UUCP protocol. But so far no one thought it was worth their time when cheap
level 3 modems are so readily available.

More than level 2 in software is difficult. You'll need a serial interface
that can do the necessary bit sychronous protocol (which will vary a lot from
machine to machine), and you'll need a synchronous modem (I *guess* the Hayes
Smartmodem 2400 would work). More effort than it is worth, and you sure won't
save any money doing it.
