Specify Variable Group for Next Attempt
This command is generated internally to specify that a specific Variable Group is to be activated for the next attempt. This command should not normally need to be entered manually: it is created when a $retry_delays command has specified an override variable group for the next attempt.
The parameter on this command is used as follows:
|groupno||The group number to be activated (from 1 to 15)|
If a transmission attempt is made, the value is not retained.
Default: no variable group is activated.
