Word Length
Sets the length of the serial data word. The length of the data word can be set
to 7 or 8 bits, and must match the corresponding data bits setting in the host
computer. The default is 8 bits.
Stop Bits
Sets the number of stop bits in the serial data word. Either one or two stop bits
can be selected. The setting must match the corresponding stop bit setting in
the host computer. The default is 1 bit.
Parity
Set for odd parity, even parity, mark, sense, or no parity. The setting must
match the corresponding parity setting in the host computer. The default is
None.
Data Term 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.
• True. Continuously asserts the DTR signal (the default).
• On-Line and BNF (buffer not full). Asserts the DTR signal when the
printer is online and the internal serial buffer is not full.
• Off-Line or BF (buffer full). Asserts the DTR signal when the printer is
offline or the internal serial buffer is full.
• False. Never asserts the DTR signal.
Request to Send
This configuration is part of hardware flow control and determines when the
Request to Send (RTS) signal is generated. This signal indicates whether or
not the printer is ready to receive data.
• On-Line and BNF. Asserts the RTS signal when the printer is online and
the internal serial buffer is not full (the default).
• Off-Line or BF. Asserts the RTS signal when the printer is offline or the
internal serial buffer is full.
• False. Never asserts the RTS signal.
• True. Continuously asserts the RTS signal.
Buffer Size in K
Configures the amount of memory allocated for the serial port buffer. The
default is 1 Kbyte, but you may specify between 1 and 16 Kbytes, in
1-Kbyte increments.
