At the Univ of Minnesota we have a modem pool (RACAL 24 something) with MNP level 3, connected to the department's Vax-780/4.3bsd. My Wyse50 terminal at home is hooked to a CTS-AMH (24 something) modem, with level 4 MNP. The CTS was solid from the beginning. The Racal-Vadics caused some initial pain, but have been functioning for several months. The Vax also needed some work. However, now communication is decent, with MNP-3 at 2400 baud rate, and I NEVER see an error. I'm not a techie as far as these things go, so I wouldn't be able to answer specific questions. For end-users like myself, the connection appears to be working fine. Some times for many many hours. Don't bury MNP, yet. Usual disclaimer -- I have no interest in CTS, Racal etc. (However, you might be interested in the price for the CTS: $325, at a local retailer.) -- Neta Amit U of Minnesota CSci Arpanet: amit@umn-cs.cs.umn.edu

Since we were in the MNP business, I have a question: I have seen an ad for a program which emulates MNP by software. (for PCDOS). According to what I know, ( and was also posted here ), MNP protocol above level 2 ( level 3 and up ) uses synchronous mode ( no start/stop bits ) in order to gain a speed increase. I understand that it's not a problem to emulate MNP level 1,2 by software, but is that possible with levels 3 and up? Can you run a synchronous protocol over a normal rs232 hardware ( say, like the PC), that will be compatible with MNP? I don't remember the level mentioned in the ad, if it was mentioned at all.
