"  This program uses the HP 54504A oscilloscope"
"  and the HP 3478A voltmeter to generate "
"  interrupts.  You MUST have these "
"  instruments connected to your computer to "
"  actually run this program. However, the "
"  techniques illustrated here apply to any" "  instruments." ""
"  Note that you must properly configure your "
"  instruments before running this program using"
"  \"I/O --> Instrument Manager\" menu selection." ""
"This is how to operate the program:" ""
"  1. Click on \"Run\" in the VEE title bar. " " "
"  2. Press the \"SRQ\" front panel button on the"
"     HP 3478A or any key on the front panel of " "     the HP 54504A." ""
"This is how the program works:" ""
"  The Direct I/O objects labeled \"scope\" and"
"  \"dvm\" reset the instruments and configure "
"  them to generate service requests (SRQs). " "  "
"  The HP 3478A will generate an SRQ when you "
"  press its SRQ front panel button; the "
"  HP 54504A will generate an SRQ when you "
"  press any of its front panel buttons.  " "  "
"  The Until Break loop  waits for an SRQ and"
"  reports the identity of the requesting " "  device when an SRQ is detected. "
"" "  Note that different steps are required to"
"  re-enable interrupts for different " "  instruments:" " "
"  * The HP 3478A requires only a serial poll"
"    to clear the RQS bit of the status byte and"
"    thus re-enable interrupts.  This is typical"
"    of older, simpler instruments. " ""
"  * The HP 54504A requires the additional step "
"    of clearing the event register that records"
"    front panel key press events.  This"
"    behavior is typical of more modern, complex "
"    instruments.  READ YOUR INSTRUMENT " "    PROGRAMMING MANUAL CAREFULLY.")))
