Parameter 12: Flow Control of PAD by Local DTE
Parameter 12 specifies whether the DTE is allowed to flow
control the PAD. Flow control of the PAD is the handled in
conjunction with S-register 54 (DCE flow control). The type
of flow control the PAD recognizes depends on the setting of
S54. For example, if S54 is set for CTS flow control, the PAD
is flow controlled when CTS is off, and resumes transmitting
data when CTS is on. If all of the DCE flow control options
are disabled (default), the PAD recognizes XON (Ctrl Q) and
XOFF (Ctrl S) as the method of flow control. The DTE flow
control of the PAD is possible if parameter 12 is set to 1 and
the PAD is in the data transfer mode.
*default
Note: The flow control off condition is canceled when the PAD
leaves the data transfer mode. The flow control off condition
does not exist when the PAD enters the data transfer mode.
Parameter 13: Line Feed Insertion after Carriage Return
Parameter 13 specifies if, and under what conditions, a line
feed character is inserted in the data stream by the PAD after
a carriage return when the PAD is in the data transfer mode.
Enabled, the line feed insertion only applies to carriage returns
transmitted to and / or received from the local DTE during the
PAD data transfer mode. The format effecter (carriage return
and line feed) of a service signal is not subject to line feed
insertion after the carriage return since service signals are not
transmitted in the PAD data transfer mode, but are transmitted
in the PAD command mode.
