Enabling Ports
To enable a port, enter this command:
pmadm -e -p<port_monitor> -s<service_tag>
For more information, see the man page for pmadm.
Disabling Ports
To disable a port, enter this command:
pmadm -d -p<port_monitor> -s<service_tag>
For more information, see the man page for pmadm.
Viewing Settings
To view the current tty settings for a port, enter this
command:
stty -a < /dev/term/portname
For more information see the man page for stty.
Baud Rate Mapping
UUCP and CU do not support baud rates above 38.4 Kbps.
Therefore, to take full advantage of the RocketPort board’s
potential speed (such as 57.6K, 76.8K, 115.2K, or 230.4K),
you must use one of the following methods to remap baud
rates on one or more ports:
•
setbaud
This program enables you to remap baud rates for one
or more ports, for the current session only.
Note: 460K is not supported.
•
baud.init
This command enables you to remap the baud rates
automatically each time the system is rebooted.
Setbaud
Follow these steps to remap baud rates for the current
session.
Note: Baud 50 through 134 are not included in the
/etc/ttydefs file. Setbaud can be used by using the -u
option to set each over 300 or by adding 50, 75, 110,
and 134 to the /etc/ttydefs file.
1.
Disable the ports for which you want to remap baud
rates.
2.
Enter this command:
/comtrol/rckt/setbaud -h /dev/term/portname
The rates are remapped as shown in the following table:
Note: The /etc/ttydefs file does not include the 50 through
134 baud rates. You need to manually add these
baud rates to the file.
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 is used
instead.
To map a port to a rate not in the setbaud table, enter this
command:
/comtrol/rckt/setbaud -u /dev/term/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/term/portname
Baud.init
Follow these steps to permanently remap baud rates:
1.
Edit the /comtrol/rckt/baud.cfg file to list the ports for
which you are remapping baud rates. To use the
remapped rates listed in the setbaud table, simply list
the devices names. For example:
/dev/term/r0a
/dev/
term/r0A
/dev/term/r0b
/dev/
term/r0B
To create a custom mapping scheme, enter the device
name, the old rate, and the new rate the old rate is
mapped to. For example:
/dev/term/r0a 9600 230400
/dev/term/r0A 9600 230400
/dev/term/r0b 9600 230400
/dev/term/r0B 9600 230400
