- I would suspect (based on having run a Hermes system for some time) that
- you have a flow control problem. This problem could be on the Hermes
- end or on the WK end. With high speed modems, ONLY hardware flow control
- gives acceptable results. No amount of fiddling with software (XON/XOFF)
- flow control will avail you. Belive me, I tried. The reason this is so
- is that XON and XOFF can be valid characters in any binary transfer.
- High speed modems have buffering for compression, and throughput is
- variable, and so they must be able to say "Hey! My buffer is full!
- hold off!"
