I use &F1 and &B1. That locks the serial rate between the computer and the modem and specifies Hardware Flow control. You fix the serial port at some rate such a 57.6kb or 115.2kb and let the modem connect at what ever speed it wants to. You have to use Hardware flow control (RTS/CTS) to block when one of the pieces is getting ahead of the other.
