I do actually, but only if it differs from what I said earlier re fax.

And WAS fixable in the Sportster with an EPROM change.

Dunno that I'd actually call that a bug though.

That's not a modem bug, but a problem with the manual,

Another manual problem.

Another manual problem.

Another manual problem.

Another manual problem.

Another manual problem.  It's AT+FAA, and is the standard command.

I'm not surprised.  You followed the manual (which is clearly wrong), and
also appear to have entered the command strings incorrectly.  Don't quote
me, but I read somewhere that you need to use the "/" character
with AA in Bink.  I paid little attention at the time though, as I wasn't
interested.

Dunno why.  There's NO reason for that to have failed, unless perhaps the
BIT was sending V.8 tones (turned on by default with some brands) which the
Viper confused with fax CNG tones, but that's just one possibility.  AA
should work with ALL modems with V.8 CI tones disabled.

Most of those problems relate to the fuckwit who compiled the manual, and
it would appear that the modem itself is actually relatively bug-free.
