Whenever a data comm configuration menu is displayed on
the screen, the terminal is implicitly in format mode. The
menu contains a set of unprotected fields that you access

This field specifies at what speed you want the data transmission to take place (in bits per second).
Values:
110
600
2400
134.5
1200
4800
150

This field specifies what type of parity generation and checking you wish used with each data
character.
Values:
None
(no parity bit)
0'5
(parity bit always zero)
DOD
(odd parity)
1'5
(parity bit always one)
EVEN
(even parity)
This field is used for enabling or disabling the parity check feature for data characters received
over the data comm line. NotethatifthePllri ty field (above) issettoNDNE, then this field is ignored.
Values:
YES
NO
(enable)
(disable)
This field specifies what number of data bits you want in each character (for both transmitting and
receiving). ASCII characters are normally passed as 7-bit data codes. Note that if you specify B-bit
data codes then NO parity generation or checking is done (regardless of what you specified in the
Pllri
ty
and ChkPllri
ty
fields described above).
Values:
