30 TCP/IP AXEL Platine Terminal
When scancode mode is switched on, the keyboard LEDs can be turned on or
off by means of an escape sequence (
CSI < p1;p2;p3 O
). For more
information, refer to the
User's Guide .
3.3 - TUNING THE OPERATING SYSTEM
The operating system TCP/IP package may not default to an optimized
configuration for the use of TCP/IP terminals. In this situation, the system
parameters may be adjusted by means of a 'tuning' procedure.
Note: to accumulate sufficient, significant information to analyze the
performance of terminals, it is necessary for the system to run, under realistic
operating load conditions, for several hours.
3.3.1 - SCO UNIX 3.2v4
Analysis of the SCO UNIX TCP/IP package is done with the following
command:
# netstat -m
This command lists characteristics of all intermediate class buffers used by
TCP/IP.
The two parameters to check are the number of buffers per class (configure
column) and the number of failures (fail column).
If a class has a non-zero 'fail' number, the number of buffers must be increased
for this class.
To modify the parameter setting for a class, enter sysadmsh and select the
following menu options:
[System]
[Configure]
[Kernel]
Within the menu, select 'Parameters - Tune kernel params'. A second menu
is displayed. Select option 11: Streams Data.
