To do any task in the following
table except List, a tty device must be installed.
| Managing TTY Devices Tasks | |||
|---|---|---|---|
| Task | SMIT Fast Path | Command or File | Web-based System Manager Management Environment |
| List Defined TTY Devices | smit lsdtty | lsdev -C -c tty -H | Software --> Devices --> All Devices. |
| Add a TTY | smit mktty | mkdev -t tty1,2 | Software --> Devices --> Overview and Tasks. |
| Move a TTY to Another Port3 | smit movtty | chdev -l Name -p ParentName -w ConnectionLocation2,4 |
|
| Change/Show Characteristics of a TTY | smit chtty | lsattr -l Name -E (to show); chdev -l Name (to change)4,5 | Software --> Devices --> All Devices --> Selected --> Properties. |
| Remove a TTY3 | smit rmtty | rmdev -l Name | Software --> Devices --> All Devices --> Selected --> Delete. |
| Configure a Defined TTY (Make Available for Use) | smit mktty | mkdev -l Name | Software --> Devices --> Overview and Tasks. |
Notes:
- Other flags may be used to further specify the new tty device. For example, to define and configure an RS-232 tty device connected to port 0 on the 8-port asynchronous adapter sa3 with the speed attribute set to 19200 and other attributes set to values retrieved from the foo file:
mkdev -t tty -s rs232 -p sa3 -w 0 -a speed=19200 -f foo- The mkdev and chdev commands support options that are not possible with Web-based System Manager or SMIT.
- Disable the tty before doing this task. See the pdisable command.
- Use flags to change specific characteristics about a tty from the command line.
- You can select a Posix baud rate from the List function, or you can type in non-Posix baud rate directly into the field. If the selected baud rate cannot be supported by the modem's hardware, the system displays an error message.
If adding or changing a tty from
the command line, consult the following list to find out the
Attribute name to specify in the
-a Attribute=Value flag for
the characteristic you want to set. For example, specify
-a speed=Value to set the baud rate of a tty device.
| Characteristic | Attribute Name |
| Enable LOGIN | login |
| BAUD rate speed | speed |
| PARITY | parity |
| BITS per character | bpc |
| Number of STOP BITS | stops |
| TIME before advancing to next port setting | timeout |
| XON-XOFF handshaking | xon |
| TERMINAL type | term |
| FLOW CONTROL to be used | flow_disp |
| OPEN DISCIPLINE to be used | open_disp |
| STTY attributes for RUN time | runmodes |
| STTY attributes for LOGIN | logmodes |
| RUN shell activity manager | shell |
| LOGGER name | logger |
| STATUS of device at BOOT time | autoconfig |
| TRANSMIT buffer count | tbc |
| RECEIVE trigger level | rtrig |
| STREAMS modules to be pushed at open time | modules |
