Configuring Eiconcard Connections for Linux
page 20
•SIG.+X.25
Choose one of these options based on the line type or modem being used.
Changing Protocol Parameters
Each protocol has a number of parameters associated with it. These parameters allow
customization of the protocol software for your particular connection. Eiconcard protocols can
be configured to suit almost any communications situation. This is done by assigning values
to the parameters in the protocol configuration screens.
Note: It is always a good idea to make a backup copy of your Eiconcard configuration file
ec.cfg before modifying any parameter values. If problems are encountered with the modified
version, the backup copy can be restored. As an aid for detecting communication problems,
log any changes you make to the original file.
Eiconcard Memory Requirements
The Eiconcard contains its own CPU, memory, and embedded operating system. The protocol
software runs on the Eiconcard, not on the Linux server. Therefore, the software options you
define for Eiconcard Connections for Linux are constrained by the amount of memory available
on the Eiconcard. This applies to protocols you define with eiconcfg or ECCLI and to the number
of Host PAD and Terminal PAD devices defined on the Linux system.
Using the Configuration Screens
The configuration screens all use specific function keys, which are listed at the bottom of the
screen. To move between parameters, use the cursor keys () or the Tab key. To change a
parameter, type the new value directly. For some parameters, you can press the Spacebar
repeatedly to scroll through the permitted parameter values.
The following table describes the function keys displayed on the configuration screens:
Alternative Function Keys
Most terminals have the function keys defined in /usr/lib/terminfo/terminfo.src.
If this is not the case, you should be able to use an alternative function-key mapping. For
example, the following function keys are normally available:
•Esc 1 Help
•Esc 2 Save
Esc 3 Previous Screen
•Esc 4 Config
•Esc 5 Previous Card
•Esc 6 Next Card
•Esc 9 Print
•Esc 0 Quit
