This may or may not qualify as a "hack" but I wish to add code to a pascal program I wrote while still in college. Simply enough all I want to do is to check to see if a terminal has /NOBROADCAST set and if so set it to /BROADCAST and then $BRKTHRUW a message and then of course reset it. The checking for /NOBROADCAST is easy. I have been scanning the system services manuals and other VMS manuals durring lunch looking for some sort of system routine to do it. ********** Is there one I am not seeing???? ************** Oh ya, the program (acually two) spawns off a subprocess and waits for a given delta time ($hiber) then $BRKTHRUW's a message. An alarm program. I use process logicals to communicate the delta time to the subprocess. Thanx, Brian (Mac)

Take a look at I/O users guide, Part I, terminal driver.
All you need to do is a IO$_SENSEMODE to the terminal. You will
receive back the characteristics buffer which, among other things,
will have the value of the TT$V_NOBRDCST bit (set if broadcasts
are disabled).
that's it.

Thanks Matt! I have been "playing" with it since I got your reply. I was not expecting such a quick response! I like the fact that the I/O users guide does almost exactly what I need! I looked at the TOOLSHED and noticed two alarm programs, one that does spawn. I will continue with mine though. It works fine now I just want to "make absolutely sure" the alarm will be seen. (reset nobroadcast). Thanks again, Brian (Mac) | |||||
