Note: This command takes no arguments
Command or Query.
Sets or queries user-defined Circuit ID string, which is 4 to 32 characters in length.
Valid characters include:
Space ( ) * + – . / 0 9 and A thru Z
Command or Query.
CnC enable in the form x, where:
0=Off
1=On
Notes:

• the optional plug-in hardware CnC card has been installed, AND
•
a CnC FAST option is unlocked.
The range of permitted datarates is controlled by a FAST feature code. (Read EID
to decode the installed options for the modem)
