Carrier Control
The modem will accept the C1 command without error in order to ensure backward
compatibility with communications software that issues the C1 command. However,
this modem does not support the C0 command. The C0 command may instruct
some other modems to not send carrier (i.e., it puts them in a receive-only mode).
