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).
* 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.
