How do I add pseudoterminals to the system?

If you have lots of telnet, ssh, X, or screen users, you will probably run out of pseudoterminals. Here is how to add more:

Build and install a new kernel with the line
```
    pseudo-device pty 256
```
in the configuration file.
Run the commands
```
    # cd /dev
    # sh MAKEDEV pty{1,2,3,4,5,6,7}
```
to make 256 device nodes for the new terminals.
Edit /etc/ttys and add lines for each of the 256 terminals. They should match the form of the existing entries, i.e. they look like
```
    ttyqc none network
```
The order of the letter designations is tty[pqrsPQRS][0-9a-v], using a regular expression.
Reboot the system with the new kernel and you are ready to go.
