Purpose
Establishes or changes the communication character (comchar) that is used to link the entry of TDP operator commands with a TDP that is to be initialized.
Syntax
The SE abbreviation is deprecated.
where:
- comchar
- Communication character as one of the following special characters:
- OFF
- Specification that no communication character be used to identify commands.
Usage Notes
When a TDP starts, no comchar is defined. After the SET COMCHAR command is executed to specify a communication character for a TDP, all TDP commands subsequently entered that are preceded by the character are interpreted as commands for that TDP.
It is not recommended that the same communication character be defined for more than one TDP subsystem. If this is done, commands prefixed by the character are processed by all subsystems that are assigned that communication character.
Example 1: SET COMCHAR
SET COM +
Completion Message 1
TDP0543 COMMUNICATION CHARACTER IS NOW SET: +
Example 2: SET COMCHAR
SET COMCHAR OFF
