No that's what I thought. According to all the checks, it is 
"connected" at 115200 (RAS status, Control Panel) and Modem.Inf 
has MAXCARRIERBPS=33600 & MAXCONNECTBPS=115200 

(Although I have never been quite sure what this concept means 
for an internal modem. For an external modem its the serial line 
speed from the far side of the Uart to the modem proper. I 
assume (wrongly?) an internal card doesn't do anything as silly 
as turning the bytes into a serial bitstream and then back again 
for the modem proper to deal with. Or does it!)

I was wondering if there was any way to "tune" the values of
MTU, RWIN and MSS in the NT 3.51 stack. I can remember long 
discussions several years ago as to the best settings for the 
Trumpet stack - and it would probably make a difference with 
highly compressed traffic.
