I do not have a loopback device 3. lsof is above my head? what should I look for? should I add any options to the lsof command? Here an interesting finding : If I run one of the modem programs (wvdial) first, then ttyS5 works, so it looks like you impression of <something is blocking the tty layer> is correct. I wonder what /etc/wvdial.conf does to unblock it? The following shows: - the first channel command does not work and hangs for ever so I killed them with Ctrl-C - second I run the wvdialconf it works as it should recognizing and configuring the modem - third I run again channel and now it works OK changing the channel to 42 and echoing the result. -------------------------------- linux-44xr:/home/tdec # channel -p /dev/ttyS5 42 ^C linux-44xr:/home/tdec # wvdialconf /etc/wvdial.conf Editing `/etc/wvdial.conf'.
