of pseudoterminals you want to add. The following examples show that
400 pseudoterminals have been added.
The pseudodevice entry for STREAMS-based pseudoterminals is as
follows:
pseudo-device rpty 655
The pseudodevice entry for clist- based pseudoterminals is as
follows:
pseudo-device pty 655
For more information on the configuration file and its its pseudodevice
keywords, refer to Chapter 5.
3. Rebuild and boot the new kernel. Use the information on rebuilding
and booting the new kernel in Section 5.4.3.
When the system is first installed, the configuration file contains a
pseudodevice entry with the default number of 255 pseudoterminals. If
for some reason the number is deleted and not replaced with another
number, the system defaults to supporting 80 pseudoterminals.
4. Log in as root and change to the /dev directory.
5. Create the device special files by using the MAKEDEV command, which
has the following syntax:
./MAKEDEV pty
#
The number sign (#) represents the set of pseudoterminals (0 to 101)
you want to create. The first 51 sets (0 to 50) create 16
pseudoterminals for each set. The last 51 sets (51 to 101) create 46
pseudoterminals for each set. You can use the following syntax to
create a large number of pseudoterminals:
./MAKEDEV PTY_
#
The number sign (#) represents the set of pseudoterminals (1 to 9) you
want to create. Each set creates 368 pseudoterminals, except the
PTY_3 and PTY_9 sets, which create 356 and 230 pseudoterminals,
respectively.
Refer to the Software Product Description (SPD) for the maximum
number of supported pseudoterminals.
_____________________ Note _____________________
By default, the installation software creates device special
files for the first two sets of pseudoterminals, pty0 and
pty1. The pty0 pseudoterminals have corresponding device
special files named /dev/ttyp0 through /dev/ttypf. The
