VS: View System Dump
Command: VS
Syntax: VS
Purpose: View System Dump. This command allows the user to
dump all important chip registers and microcode data
structures to the screen. It is probably the most useful
command for debugging. The dump is continuous with
no pauses and is meant to be dumped to a log file. The
user should open an output file (F1 under PCPLUS or, if
using windows, open terminal and enter Receive Text File
in the Transfers... menu). Data will scroll by until the
monitor’s > prompt is reached. The log file should be
closed. Call technical support for help.
