set baud
The set baud command sets the baud rate on the RMC modem port and on the
COM1 to microcontroller port. Allowed values are 1, 2, and 3. Note that the
microcontroller port that is connected to the 6-pin MMJ connector for the local
console terminal is not affected. This port is fixed at 9600 baud.
It is important that the baud rate being used by the operating system or console
(com1_baud) be changed before using this command; otherwise the remote operator
will not be able to communicate with the system.
Consider the following before changing the baud rate:
• The value of the SRM com1_baud environment variable is saved in nonvolatile
memory, while the value of the RMC set baud command is not. If you have
changed the baud rate and the power fails, the RMC modem baud rate will
return to the default value (9600) and the com1_baud rate would have to be
changed locally before a remote dial in could be reestablished.
• The ECU and RCU configuration utilities only run at the 9600 baud rate setting.
• DIGITAL UNIX requires that a file be edited to match the new baud rate, or the
operating system will not reboot successfully.
The following example uses the SRM console.
NOTE: If a modem is being used, the enable remote command must be issued
following the set baud command in order to set the modem to the new baud
rate.
Example:
>>> show com1_baud
com1_baud 9600
>>> set com1_baud 38400
^[^[RCM
RCM> set baud
baud (1=9600, 2=19200, 3=38400)>3
RCM> quit
Returning to COM port
>>> show com1_baud
com1_baud 38400
>>>
