• If AT^SMSO is entered on one of the Multiplexer channels the ME closes the Multiplexer channels, terminates

the Multiplexer and deactivates all other functions. Then, the URC "

^SHUTDOWN

" will be issued on the phys-

ical serial interface (ASC0). The URC will be transmitted at the bit rate last activated on ASC0 for use with

the Multiplex driver.

• If both interfaces ASC0 and ASC1 are connected the URC appears on both of them.
