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 if the
printer is ready to receive data.
• True. Continuously asserts the DTR signal.
• 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.
• On-Line. Asserts the DTR signal when the printer is online.
• 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.
• Off-Line or BF. Asserts the RTS signal when the printer is offline or the
internal serial buffer is full.
• On-Line. Asserts the RTS signal when the printer is online.
• False. Never asserts the RTS signal.
• True. Continuously asserts the RTS signal.
Buffer Size In K
This option configures the amount of memory allocated for the serial port
buffer. You may specify between 1 and 16 Kbytes, in 1-Kbyte increments.
NOTE: If you select a baud rate that is 19200 or greater, you may need to
increase the Buffer Size In K parameter from the default to 16 Kbytes
to improve performance.
Poll Character
This option is for the Series1 protocol. Whenever the printer receives this
character, it sends a response to the host indicating the current state of the
printer (see Series1 protocol). It may be configured from 0 through FF
hexadecimal.
