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

And you still haven't, I notice.

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...
