Paul, at 09:02 on Feb 02 1996, you wrote to David Drummond...

It fucking *IS*, Paul. Read the following quotes VERY carefully...
===================================================================
Word length* 8
Parity* 0 None
DTE rate* (Kbps) 19.2
* Detected by the modem from the AT prefix of the &W command that
writes your defaults to NVRAM. Set your software to the desired
word length, parity and serial port rate defaults before sending
the modem the AT . . . &W string.
====================================================================
&Bn = Serial port rate variable or fixed.
&B0 Variable rates. When the modem switches its connection rate
to connect with a modem operating at a different rate, it also
switches its serial port rate. The software or terminal also
switches serial port rates to match the connection rate.
&B1 Fixed rate. Default. The modem always communicates with the
terminal or computer at the rate at which you have set the
terminal or software, regardless of the connection rate.
For the greatest throughput, set the serial port to 115.2K,
57.6K, 38.4K bps for high speed calls and to at least 9600
bps for 2400-bps calls.
This setting is not affected by the &N setting. However, the
serial port rate must be equal to or higher than the &Nn rate.
&B2 Fixed for ARQ calls/Variable for non-ARQ calls. Answer mode
only. When the modem goes off hook and connects in ARQ mode,
it shifts its serial port rate up to a user-specified rate, for
example, 38.4K bps. If the connection is not under error
control, the modem behaves as if it were set to &B0 and switches
its serial port rate to match the connection rate of each call.
To implement this feature, first set your software to the desired
rate. Then send the modem the AT &B2 [other settings] &W command.
The modem stores the rate of the command in NVRAM along with the
settings. Each time it makes an ARQ connection, the modem checks
NVRAM for the specified serial port rate.
When sending subsequent configurations to NVRAM, be sure your
software is set to your selected serial port rate, so that the
correct rate is maintained.
==========================================================================
PE> It is a bug.
Oh crap. The only bug there appears to be up your arse...
