Compaq 5525B, 5532, 5531 user manual Request to Send, Buffer Size in K

Serial Submenu

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.
