equivalent of a dial tone from the PBX.
See Also: Chapter 4, “Operation and Configuration.”
Register: S8 — not used
Register: S9 — not used
Register: S10
Description: The value in this S-register determines how long the 7400B Data
Module will wait after loss of line signal is detected before
disconnecting.
Range of Value may be 000 through 255 tenths (0.1) of a second; factory-default
Values: value is 014 tenths of a second (1.4 sec.).
Storable: no
Comments: The delay set by this S-register allows the receive line signal to
disappear momentarily without causing a disconnect (hang-up).
Setting this S-register to the maximum value (255) causes the Data
Module to ignore receive line signal status and not disconnect the data
call if line signal is lost.
