flexfax: Unspecified Transmit Phase B error

[Mark Porporino <mporporino@hotmail.com>]

I have HylaFAX compiled for Solaris 2.5 and use gcc 2.7.2, HylaFAX
v4.0pl1, a external USR Sportster Voice modem, and I see the following
in a trace log:

bp4Uec 18 06:22:41.90: [ 6167]: --> [65:'IOd~-
gNrft
 t  ko^
              }OJ jsx]
Dec 18 06:23:21.91: [ 6167]: REMOTE HANGUP: Unspecified Transmit Phase B
error (code 20)

All I need is sendfax capability - 'sendfax -d 2223333 /tmp/foo.ps'

I've tried both RTSCTS and XONXOFF flow control and the modem is set
to faxtory defaults.

Also, when I run 'faxsetup', I get a (something like this), "your modem
is hanging, better check it out", message, but no explanation of what
it means.

My modem seems to work fine otherwise.

Thanks
