I don't know if you can do this or not, but here's the prob: I am trying to send a fax to a answering machine that has the capabilty of accepting faxes. But the douchbag's message is forever long and my fax machine times out and hangs up before I get the chirp to send the fax (must have the same patience level as myself). Is there any way you can change the settings to prolong the amount of time your fax machine will wait for a response? I can't seem to find anything on the TX settings just poking around on it. Still looking for the manual.
