To do any task in the following table except List, a tty device must be installed.
| Managing TTY Devices Tasks | ||
|---|---|---|
| Web-based System Manager:    wsm devices 
fast path (Devices application) -OR-  | ||
| Task | SMIT Fast Path | Command or File | 
| List Defined TTY Devices | smit lsdtty | lsdev -C -c tty -H | 
| Add a TTY | smit mktty | mkdev -t tty1,2 | 
| 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 | 
| Remove a TTY3 | smit rmtty | rmdev -l Name | 
| Configure a Defined TTY (Make Available for Use) | smit mktty | mkdev -l Name | 
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. Refer to the pdisable command.
 - Use flags to change specific characteristics about a tty from the command line.
 
If adding or changing a tty from the command line, consult the following list to find out the Attribute name you should 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 |
