timeout on dialing

[tyche ica net]

how does one increase the timeout on dialing in sendfax?
i am trying to send a fax, the fax on the other rings 4 times, handshaking is 
started, then sendfax disconnects with an error 10. (no carrier). this is 
iritating.

also using the network configuration utiltity from redhat, my internet dialer 
dies from inactivity while i am reading a webpage. how to stop this.
