Printronix Series 5 - Manual (Page 161)

4–108 Configuration Menus
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.
•
True continuously asserts the RTS signal.
•
False never asserts the RTS signal.
•
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.
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 Series 1 protocol. Whenever the printer receives this
character, it sends a response to the host indicating the current state of the
printer (see Series 1 protocol). It may be configured from 0 through FF
hexadecimal.
Poll Response
This option is for the Series 1 protocol. After receiving a poll character, the printer
will wait the poll response number of milliseconds before sending the response. It
may be configured from 0 through 30.
