D-Channel X.25

Parameter 8: Discard Output

Parameter 8 specifies whether data received by the PAD from the remote end is transmitted to the local DTE device. The control of data delivery is only possible when the PAD is in data transfer mode (i.e., this is the mode when data is being delivered to the local DTE device).

Table 12-14: Discard Output

Value Description

0Normal data delivery *

1Discard output to the DTE

*default

Parameter 9: Padding after Carriage Return

		Parameter 9 specifies the number of padding (null) characters
		inserted after a carriage return, which is transmitted or echoed
		to the local DTE device. This provides the printing mechanism
		of the local DTE device time to physically complete the
		carriage return (advance the printing head to the beginning of
		the line). Once complete, the PAD can resume sending data to
		the local DTE device without losing data.
		Parameter 9 also applies to the number of padding characters
		inserted after the format effecter (carriage return and line feed).
		The format effecter is sent in conjunction with PAD service
		signals to the local DTE device when the PAD is in PAD
		command mode.
