S-Registers
C-16 Issue 2 November 1996
Register: S9
Description: This S-register establishes the length of time a receive
carrier signal must be present to be recognized and
cause the Data Carrier Detect (DCD) circuit to turn on.
This prevents a ring or busy signal from being mistaken
as a carrier.
Range of Values: Value may be 000 through 255 tenths of a second;
factory-default value is six tenths of a second.
Storable: no
Comments: This feature is unnecessary in the DCP operating
environment of the 8400B Plus Data Module. The value
in S9 may be set or read but is always ignored.
See Also: none
