5. Look in /etc/ttytype for the listed console port information. You should see lines
similar to this:
?iris-tp console
iris-tp tport
?vt100 ttyd1
?vt100 ttym1
?vt100 ttyf1
?vt100 ttyd2
?vt100 ttym2
?vt100 ttyf2
?vt100 ttyd3
?vt100 ttym3
?vt100 ttyf3
...
6. The default terminal type for all terminals is VT100, and the system prompts you to
confirm this. To keep the system from asking you what type of terminal you are
using when you log in, remove the question marks from all lines in the file that
correspond to the serial port 1, 2, 3, and 4). For example, to prevent the system from
prompting for a terminal type on port 3, change these lines in
/etc/ttytype :
...
vt100 ttyd3
vt100 ttym3
vt100 ttyf3
...
You can also change the terminal type designated for the particular serial port by
changing “vt100” to another shorthand terminal name. See Appendix C,
“Supported Terminals” for a list of some terminals and shorthand names.
7. Add the following line to your ~/.login or ~/.profile file. This sets the terminal type,
syntax, erase, and kill parameters automatically when you log in:
eval ‘tset -s -Q’
8. Check terminal connection and function using the following commands:
echo Hello, this is a test > /dev/ttyd3
This command should cause the sentence “Hello, this is a test” to appear on the
terminal attached to port 3. If nothing appears on the terminal, check that you are
using the correct serial port and that the terminal is configured correctly. If gibberish
appears on the terminal screen, it probably means the terminal is not set to the same
baud rate as the serial port.
