Rod, at 10:13 on Feb 06 1996, you wrote to Bill Grimsley...

Apparently it's only Paul who considers it a major problem anyway.

It's certainly quirky, no argument with that at all, but although I've
owned several USRs _and_ Rockwells, I've never found it to be a problem. 
Indeed, I never even noticed that its behaviour was different on USRs until
Paul started complaining about it.

Precisely.  If powered down of course, the modem will revert to that port
rate which was last specifically saved to NVRAM with an &W command.

RS> Oh sure, no one has ever disputed that there isnt a viable workaround.

Aside from Paul, who still considers it to be a bug.  :)

RS> Which presumably means you agree about a modem power cycle.

Oh sure, the port speed is only altered for that one session.

BG> Unlike ATZ, AT&F1 allows the serial port to auto-baud correctly,

RS> Or you could just have ATZ^M AT^M as an init string etc.

True.  ATZ|~~AT| actually, but that would work just as well.
