executed for at least 2 seconds.

• in front of a network for "Transfer Mode",
• in front of a CMU tester for all other modes.

3.2 Multiplexing Mode
3.2.1 Description
The AT+CMUX command is used to manage (enable or disable) the 3GPP TS 27.010
multiplexing protocol control channel. It allows to multiplex up to 4 logical channels
on a single UART. Two UARTS are available on Wireless CPU
®
s, but multiplexing can
apply to only one. The client application may handle, by this mean, up to 5 channels
(4 logical multiplexed channels on a UART, and 1 physical channel on the other
UART).
Notes on speed and autobauding:
o The response is returned at the speed of the received AT+CMUX command (prior
to entering <mode>).
o It is recommended that whenever the multiplexer control channel is released,
the Wireless CPU
®
should assume an interface rate for autobauding purposes
irrespective of any previous higher speed having been selected.
o If a +CMUX command is issued whilst in any multiplexer mode then that +CMUX
command is ignored and the Wireless CPU
®
will return an +CME ERROR: <err>
response.
