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. -- Peter R Cook PCook@wisty.demon.co.uk 100070.1313@Compuserve.com
