Baud Rate
The MSS and attached serial device, such as a modem, must agree on a speed or baud rate to use for the serial connection. Valid baud rates for the

The MSS supports Autobaud, which allows the serial port to match its speed to the attached serial device upon connection (see Change Port Autobaud in the MSS Reference Manual for an explanation of the baud rate negotiation process). Autobaud is disabled by default, but can be enabled with the following command.

Character Size, Parity, and Stop Bits
The default character size of 8 data bits can be changed to 7 data bits. Similarly, the default stop bit count of 1 bit can be changed to 2 bits. Parity is normally None, but can also be Even, Mark, Odd, or Space. To change these parameters, use the following commands:
