Response:
OK
Purpose: Set the port number to use for the SIO port.
• Query: AT!CSDONSIO2?
Response:
<port#>
OK
Purpose: Return the port number currently used for the SIO port.
Parameters:
<port#> (Port used for circuit-switched data):
• 0=CSD on main AT port (Default)
• 1=CSD on MUX1
• 2=CSD on MUX2
• 3=CSD on MUX3
