Data Bits
The DATA BITS parameter sets the length of the serial data word. The length
of the data word must match the corresponding data bits setting in the host
computer.
•
8 BITS (the default)
•
7 BITS
Stop Bits
The STOP BITS parameter sets the number of stop bits in the serial data
word. The setting must match the corresponding stop bit setting in the host
computer. One (1, the default) or two (2) stop bits can be selected.
Parity
The PARITY parameter setting can be set for the following:
•
NONE (the default)
•
ODD
•
EVEN
•
MARK
•
SENSE
The setting must match the corresponding parity setting in the host computer.
Data Terminal Ready
This configuration is part of hardware flow control and determines when the
DATA TERMINAL READY (DTR) signal is generated. This signal indicates
whether or not the printer is ready to receive data.
•
READY AND BUFFER NOT FULL (the default) asserts the DTR signal
when the printer is READY and the internal serial buffer is not full.
•
NOT READY OR BUFFER FULL asserts the DTR signal when the printer
is NOT READY or the internal serial buffer is full.
•
FALSE never asserts the DTR signal.
•
TRUE continuously asserts the DTR signal.
NOTE: When the printer is attached to an AS/400, the DTR should be set to
154
TRUE.
