the AT command sequence (usually “+++”), because the AT time will occur faster than the

Configuration
n enabling Multi-Streaming Modes (by setting the MD (RF Mode) parameter to 1 or 2), o
meter values are automatically modified to support the mode. For example, when the MD
meter is changed to 1 or 2, the RR parameter is changed to 0x0A (hex). The modification
occurs if the RR parameter is 0 (its default) before the MD command was executed. If any
r value is found for the RR parameter, the RR parameter will not be changed. Auto

CGP and DGP packets will be sent RR times to begin and end the global connection
ectively. The connection can be terminated by CE, CB timers, DI3 or ATD
other connections.
