-L Lock on a Specific Channel

Permits the DART to override normal Radio Resource Management functions and lock itself on a specific channel.

This is useful at Trade Shows where exhibitors are often requested to operate on a specific channel. It is also helpful during initial testing when it sometimes is necessary to seek out a specific channel.

The modem continues to operate on the assigned channel until the lock is removed, changed to another channel, or bit 2 in S-Register 60 is turned off.

Format:
AT-L<n>	Locks the modem on channel <n>
AT-L-	Releases the channel lock
Result codes:
OK	Valid argument
ERROR	Invalid argument
NOT ENABLED	Modem is not in service provider mode
