Serial Port Configuration Configuration
4 - 6
4.4 Serial Port Configuration
The serial port is set at the factory for 9600 baud, 8 data bits, one stop bit, and no parity. These and
other serial port features can be configured as shown below. Remember that ports should be
logged out after configuration.
NOTE: The console port is not user-configurable.
4.4.1 Access Mode
The serial port’s access mode controls what type of connections are allowed. Local access allows
the port to initiate connections to services, and will permit local logins. A port set for Remote
access will accept connection requests but will not permit local logins. A Dynamic port (the
default) can initiate and receive connection requests. To change the serial port’s access mode, use
the Change Access command.

4.4.2 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 MSS are 300, 600, 1200, 2400, 4800, 9600 (the
default), 19200, 38400, 57600, and 115200 baud. The baud rate can be changed with the Change
Speed
command followed by a baud rate number.
Figure 4-15: Changing the Baud Rate
The MSS1-T and MSS1-T2 support Autobaud, which allows the serial port to match its speed to
the attached serial device upon connection (see Change Autobaud on page 6-3 for an explanation
of the baud rate negotiation process). Autobaud is disabled by default, but can be enabled with the
following command.

4.4.3 Parity, Character Size, 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:
