7 Select [Advanced options].
8 Select [Pseudo ttys]. The default value is 32. Change the value to 256.
9 Compile the kernel.
# /etc/conf/bin/idbuild -B
10 Reboot the FEP.
# init 6
Then, the system can support up to 256 pseudo terminals.
You can also increase the number of pseudo terminals by installing programs
■
acp and update as follows:
1 Change the value of kernel parameter NUMSCOPT to 256.
# /etc/conf/bin/idtune NUMSCOPT
2 Install the acp package, which is in the first disk for SCO UnixWare. Select a
terminal number of 256 during installation.
# pkgadd -d cdrom1 acp
3 Install the update package, which is in the second disk for SCO UnixWare.
# pkgadd -d cdrom1 update711
After installation, the system rebuilds the kernel and reboots automatically.
Modifying the maximum number of files a process can open
By default, each SCO UnixWare process can open up to 64 files. If a Unix server is
to be connected with a large number of terminals (usually more than 50), you are
recommended to change the value to 400. To do so, use the following commands:
# idtune SFNOLIM 400
# idbuild -B
Modifying the maximum number of processes a user can open
By default, each SCO UnixWare user can open up to 80 processes. If a Unix server
is to be connected with many terminals (usually more than 50), you are
recommended to change the value to 500. To do so, use the following commands:
# idtune MAXUP 500
# idtune NPROC 1000
# idbuild -B
Locate the line starting with "9600:" in file /etc/ttydefs. If the echoctl option is
present, set it to -echoctl. If Chinese cannot be used normally, add the -istrip
option to the line. For example:
9600: 9600 sane imaxbel iexten -echoctl echoke -istrip -tabs ::: 4800
To run ttyd on the SCO UnixWare system, you do not need to configure pseudo
terminal related parameters in file /etc/inittab.
