Chapter 3 SERIAL PORT
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 (factory default). 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.
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).
The range is 00-FF Hex, and the factory default is 00 Hex.
Poll Response
This option is for the Series1 protocol. After receiving a poll character, the
printer will wait the poll response time in milliseconds before sending the
response.
The range is from 0 to 30 ms, and the factory default is 0 ms.
Idle Response
This option is for the Series1 protocol.
• Disable (factory default).
• Enable. The printer sends a response character every two seconds while
the number of valid bytes in the buffer is less than 75 percent of the buffer
size.
