TTGEN - ZCOM System Table Generator
Creating the TTGEN Configuration File
Option
The physical terminal option words may be set by specifying “OPTION”
(case-insensitive) with the required value after a Term or Pterm
definition. The lower 8 bits of the first option word and all 16 bits of any
subsequent words are used in terminal configuration in the ACC card
during ZCOM system startup. Their use and meaning is protocol
dependent. Refer to the relevant protocol reference manual for details.
The default value for the first word is obtained from the device table. The
default value for a ll subsequent words is zero.
Option opt-word [optional-opt-word]
Pterm
A method of defining a physical terminal which has a number of logical
terminals associated with it. The subparameter Term, above, creates a
one-to-one correspondence of physical terminals to logical terminals.
Thus Pt erm consists of a subset of the subparameters used for the Term
parameter. (See under Term above.)
Pterm in:p type poll select [callno]
Lterm
Each logical terminal that is to be linked to the physical terminal, as
described in Pterm above, must be defined in this section under this
parameter. The logical terminal subparameters are a subset of those that
occur i n the Term parameter of the Terminal-Definition section of the
TTGEN configuration file. (See under TERM above.)
Lterm ZLU type logical_address appl inst brnch work area “desc”
logical-address A hexadecimal field up to 20 hex digits (i.e., 10 bytes).
It is intended to be used by application programs to
associate unique IDs to LTERM terminals that belong
to the same PTERM terminal. The ZCOM routine
ltfind is provided to search a group of logical terminals
for a specific logical address field.
