NAME

vpmstart, vpmsnap, vpmtrace − load the KMC11-B; print VPM traces

SYNOPSIS

vpmstart device n [ filen ]

vpmsnap

vpmtrace

DESCRIPTION

Vpmstart writes filen (a.out by default) to the KMC11-B specified by device.

The argument n is a magic number that the KMC11-B driver saves to identify the running program.  This number is checked when the VPM driver is opened to provide some assurance that the program running in the KMC11-B is the one expected.  The magic number for VPM interpreters is 6.  When filen has been written to the KMC11-B, its execution is begun.  Filen may be any file executable by the KMC11-B. 

If filen is made using vpmc(1C), the VPM interpreter will be started by vpmstart. The VPM interpreter waits for a RUN command from the VPM driver before beginning execution of the protocol script.  The RUN command is sent by the VPM driver when the corresponding VPM device file is opened. 

Vpmsnap opens the trace driver (minor device number 1) and reads and prints time-stamped event records until killed. 

Vpmtrace opens the trace driver (minor device number 0) and reads and prints event records until killed.
