  Thanks for your help, David.

  I found the problem at the hylafax faxgetty.  My modem (USR Courier) is
configured to work with software handshake (hylafax docs says it does not
work in fax mode with hardware handshake), and though slip did change the
line setup, the modem did'nt...

  I disabled hylafax, put the modem in auto-answer mode, configured the line
for plain modem (/etc/rc.serial) and started plain old getty.  Everything
is fine now (except I don't have fax services anymore. :( ).
