Command Description

The test command returns a list of quadruplets, each representing an operator present in the network . Any of the

formats may be unavailable and will then be an empty field (,,). The list of operators comes in the following ord er:

Home network, networks referenced in SIM, and other networks.

The read command returns the current <mode> and the currently selected operator. If no operator is selected ,
