Locking the Port Speed Lock the speed of the modem to the speed of the auxiliary port on the System Controller. Note Make sure to turn off automatic baud rate detection because the modem speeds must be set to a fixed value. In the modem documentation, vendors use terms such as, port-rate adjust, speed conversion, or buffered mode. Enabling error correction often puts the modem in the buffered mode. Misconfiguring flow control for software or setting no flow control can result in hung sessions and loss of data.
Modems differ in the method they use to enable hardware flow control.
