Baud Rate Mapping
Older versions of UUCP and CU do not support baud rates above
38.4K bps. (This was corrected in 5.0.4c.) Therefore, to take full
advantage of the RocketPort or RocketModem board’s potential speed
with either older or current versions, use one of the following methods
to remap baud rates:
• setbaud
This program enables you to remap baud rates for one or more
ports, for the current session only.
• baud.init
This command enables you to remap the baud rates automatically
each time the system is rebooted.
Setbaud
Follow these steps to temporarily remap baud rates:
1. Disable the ports for which you want to remap baud rates.
2. Enter this command:
/comtrol/rckt/setbaud -h /dev/portname
The rates are remapped as shown in the following table:
3. Repeat Step 2 for each port for which you are remapping rates.
4. Use the normal tty administrative procedure to set the port to the
system rate. The setbaud rate will be used instead.
To map a port to a rate not in the setbaud table, enter this command:
/comtrol/rckt/setbaud -x /dev/portname oldrate newrate
Where oldrate is the system rate and newrate is the desired new rate.
To reset a port to standard system rates, enter this command:
/comtrol/rckt/setbaud -n /dev/portname
