Re: 3com/USR Prof Msg Modem: pages squished/fax aborted



> 	3com/USR Professional Message Modem, latest firmware (V.90)

Does Professional mean Courier or is it intended to make the Sportster
sound posher than it is.

                            ^^^^^^^^^^^^^^^^
This is your problem, as confirmed by:

> Apr 05 20:42:21.56: [ 8268]: REMOTE best rate 9600 bit/s

> Apr 05 20:42:27.66: [ 8268]: --> [7:CONNECT]
> Apr 05 20:42:27.66: [ 8268]: SEND begin page
> Apr 05 20:42:27.66: [ 8268]: <-- data [1026]

> Apr 05 20:42:35.65: [ 8268]: SENT 17877 bytes of data

> Apr 05 20:42:35.65: [ 8268]: <-- data [2]

Which is 8 seconds for 17877 bytes, or rather more than 20,000 bps,
which would require an extremely large amount of buffering in the modem
to avoid an overrun.  (There is some buffering in the OS, as, otherwise,
you wouldn't get more than 19,200.)
