Vidikron VP-6500VHDA manual Command, Value Description Min/max Stored?

Serial Communications

Table 6-1lists the RS-232 command set. The “Parameter (min/max)” column shows the valid parameter ranges, or “NA” for commands that take no parameters.

When you enter a valid command, the VHD Controller executes it and acknowledges it with a plus sign on the command line (+ >). When you enter an invalid command – one that is misspelled or followed by values outside the valid range for that command – the VHD Controller ignores it and returns a minus sign (- >).
