-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.
