Multi-Tech Systems, Inc. AT Commands for EDGE Modems (S000371G)
The AT^SALS command is designed to support Alternate Line Service. This allows the
subscriber to use two voice numbers on the same SIM card (service requires a dual line
SIM card).
The write command enables or disables the presentation of <view> and specifies the
<line> used for outgoing calls.
The read command returns the presentation mode of <view> and the currently selected
<line>.

The AT^SHOM returns the homezone state. The result is valid only, if network registration
state <stat> is 1 (registered) (see AT+CREG).
The feature is available only for supported network operators (02 Germany) and requires
a suitable SIM card. If the homezone feature is not supported by the network operator or
SIM card, result is always 0.
