Does anyone have any comparative data between running a fast uucp connection with an NS16550A port with the FAS driver versus one of the smarter serial cards? I'm interested specifically in the system loading and the uucp throughput. I have a suspicion that the difference is be very small, but I don't have any way to find out for sure at the moment. Thanks. -- Richard Foulk richard@pegasus.com

I don't have any numbers for you - but I can tell you that we are running with a Computone Intelliport here on nstar - and with 4 high speed modem sessions running - the system is just as fast as without any modem connections (it boogies regardless). We were some time ago using FAS - the serial IO was fast - but the system would appear to get bogged down with 4 high speed modems all going full blast (with high speed connections).. -- Larry Snyder, Northern Star Communications, Notre Dame, IN USA {larry@nstar, uunet!sco!romed!nstar!larry, nstar!larry@ndmath.math.nd.edu} backbone usenet newsfeeds available Public Access Unix Site (219) 289-0282 (5 high speed lines)

Well, I have observed a big difference. I had a serial card with no 16550, and I got olny about 700 bytes/sec., with the 16550 I now have up to 1800 bytes/sec. And I don't think I'm the only one who experienced this...
