Three control functions allow you to define which charac-
ters the wireless station can send to the host. Table 8-43

Guarded Area Transfer Mode (GATM)
The guarded area transfer mode control function selects
whether the wireless station sends all characters or only
unprotected characters to the host. When GATM is unpro-
tected (reset), the wireless station sends a record separator
(RS, 1E hexadecimal) to the host in place of a protected
field. Table 8-44 lists guarded area transfer modes.
