It seems a shame to only utilize >half the potential bandwith of my Trailblazer + The problem is that if you close a serial port (like you do when stty finishes) the serial port resets itself to its default settings (a generic Unix problem). To use UUCP at 19200 (as I do on my Telebit) put an entry for the line in /usr/lib/uucp/L-devices (at 19200) and an entry for the remote site also at 19200. Unfortunately cu doesn't seem to understand a speed of 19200 and it chokes so you can't do your own callouts at this speed (something Apple should fix in a future release ....) [although you probably could do a cu then a stty after cu had started - something like (sleep 30;stty 19200
