Sorry, I should have said this is an *INTERMITENT* problem, but it
occurs more often than not.

Yes, this could be it. I will try it tonight. I am at a client's
right now.

There seems to also be trouble trying to run the modem at different
speeds depending on the ring pattern received. That is why I used
115200; I want that speed when doing a PPP connection.

I will let you know what happens after I increase the
FAX_COMMAND_DELAY value. Thanks for your help!
