Re: flexfax: Probemodem errors? - stty command

[Harry Holt <hholt@home.com>]

On my system (Debian distribution), the stty command (part of GNU sh-utils 
2.0) works on the current terminal device (stdin) by default, thus the 
response "stty: standard input: unable to perform all requested operations"

To hang up modem lines, you would need to do:
     stty -F /dev/ttyS0 hup
