go ON for 2 seconds and then OFF for 4 seconds until the call is answered by 
the host. When the host turns DTR ON, the DAC answers the call. If 
DM-to-DM protocol exchange is successful, the DAC drives CTS, DSR, and 
DCD ON. If DTR was already ON, the DAC does not drive RI ON.

This mode should be selected when the DAC is connected to a host for host 
accessing. In this mode, the DAC operates in a similar manner to the MCDS. 
The hosts used with this mode should have the following characteristics:

Auto-answer capability The host should be capable of monitoring the RI 
lead for detection of incoming calls. When RI is turned ON by the DAC, the 
host responds by driving DTR ON, which forces the DAC to answer the 
incoming call. If the host drives the DTR lead ON all the time, incoming calls 
will always be immediately answered and the RI lead will not be turned ON 
by the DAC. If DM-to-DM protocol exchange is successful, the DAC drives 
CTS, DSR, and DCD ON.
