Configuring the Terminal
Table 3-4. Datacomm Configuration Menu Fields (Continued)
This field specifies the desired number of datacomm buffers to
be used for
the terminal. The permissible values are 2 through
16 (your actual choice, however, can be affected by the selected
buffer size; see BufSi ze). The designated buffers will be used
for
both receiving and transmitting data.
Default=2
This field specifies the desired state of the RS-232C TR line
(Data Terminal Ready) when the terminal is first turned on or
when the terminal is reset. Whenever the terminal performs a
disconnect, it also returns TR to the state specified by this
field.
For configurations in which the Full Duplex Hardwired menu
((RecvPac i ng" field is set to ((TR( CD)", the TR line is used to
control receive pacing.
Values:
Hi
Lo
Default=Hi
Check Parity
(Pt-to-pt

BCC
(Multipoint
only)
This field is used for enabling or disabling the parity check
feature for data characters received over the datacomm line.
Note
that if the ((Pa r i t y" field (above) is set to ((None", this
field is ignored. If the ((Da taB its" field is set to ((8", this field
must be set to uNone".
Yes: enable
No: disable
Default=No
Selects CRC (cyclic
redundancy check) or LRC <longitudinal
redundancy check) type ofblock checking. The selection used
should be the same as that used by the drive'! program in the
host computer. (The HP 1000 and HP 3000 computers use
CRC.)
