Never had that problem, then again, all the machines I've used are running FreeBSD 2.2.5 or later - have you considered upgrading, or at least trying mpd on a FreeBSD-more-recent-release? > 2) Not matter how many modems (1 or 2) we try to connect and no matter what > "Connect" speed is reported back by the chat script, the "bandwidth" report > is always 9600.

I'd check your config carefully again, email me off-list if this persists, I can dig up an old working config from a customer's server at work (only two modems per end, but it certainly reports the bandwidth at a much higher rate than you describe). > Also, a "ping" between the units is always around 150ms regardless of the > number of modems that have actually linked. MPPP increases bandWIDTH, not transmission time. The pipes still have the same speed characteristics (round trip time, latency, call it what you will), there's just more of them to carry data in parallel.
