A number of modems now offer MNP Class 5 data compression and
MNP Class 4 error control. I would like to know how widespread is the
host support and use of MNP modems.
I am thinking about upgrading to an MNP modem, but it seems like
the systems I normally use do not support MNP modems. Any experiences
with these modems?
Thanks in advance for your responses.

If you are buying a modem today, I would ensure that you get MNP. You might not use it all the time, but you will always be prepared. I have 5 modems attached to our system, all of which are mnp and one of which is a T2500 which I use for uucp connections. -- Conor P.

I use the PM2400SA MNP from Practical Peripherals. After a week or so of experimentation, the modem now communicates with every system I've tried. MNP is used if supported, otherwise just standard 2400bps. The only problem I've seen is that there is sometimes a problem getting block-oriented file transfers to work. (YMODEM, etc) with non-MNP modems. These problems are minor, but did not exist when I ran the modem in non-MNP mode with the same systems. In Telix 3.12, it is possible to have different dialing prefixes for different systems on the dialing list (four codes intended for Long Distance access are provided). Set one up for MNP systems, and another for non-MNP, and you've got the best of both worlds. ---------------------------------------------------------- Gordon S.

About half a year ago there was discussion about MTE terminal program, and several posters informed that it is NOT shareware, but fully commercial. Unless things haven't changed since then, and assuming that the information was correct, this means that MTE may not be distributed through ftp sites nor bulletin boards. Some SysOps were even admonished for keeping commercial wares up for download. ...................................................................
