Subject:   Thruput at 28.8 slower than 24.4. Huh?

Okay, first my setup:

- FreeBSD 2.1 running IIJPPP w/tun0 running at 750 MRU
- Supra 28.8bps external FaxModem w/latest ROMS, hi-speed UART, etc
- Connected to Port Livingston terminal servers w/US Robotics
Courier v.Everything's

When the receive speed of my modem is set to 24.4 - 26.6bps,
everything is smooth as silk.  When I get a true 28.8 connection,
however, my throughput slows down to about 1/10th the speed it was
running at w/26.6bps or below.  At 28.8, I'll get a burst of
something, then nothing for a couple seconds, then another burst,
etc.  At 26.6 data just streams away.

Any ideas from the software side what this might be before
suspecting hardware?
