The ??DIALT (Dial Trace) command initiates DIAL tracing.
Note: | The ??DIALT command is intended for use by Unisys engineers. This command is not supported for use by customers. |
Syntax

Explanation
The first time any ??DIALT command is entered, the MCP allocates the DIALTRBUFFER array to hold the statistics. The + and − options turn the statistics-collecting operation on and off. When the data array is full, all statistical data gathering is automatically stopped, as if a ??DIALT − command had been entered.
??DIALT
Reports the current status of the DIAL trace (on or off).
??DIALT RESET
Reinitializes the data array, discarding any currently stored data and stopping all statistical data gathering.
