Module 9261 Sending events

With this module you can send events to a spawn or submit job and then

interrogate them with Module 9260. You can call the module in the cyclic

program section, in submit jobs and in spawn processes. The TNC addresses

the receiver through the identifier that the spawn command has returned. The

submit queue is addressed through the identifier $80000000 (not through the

identifier returned by the SUBM command!). The TNC always assigns the

events that you send to the submit queue to the job that is running at the time

of arrival. If they are not read by this job, they remain for the next one. If you

wish the receiver process to start immediately, after Module 9261 you must

also call Module 9262 to enable a change of context.

Event bits 16 to 31 are reserved for the operating system (see Module 9260).
