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.
•
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.
