Transceiver Mode
The transceiver mode selection shows the transceiver mode in use, and
applies only to AT-485 boards and PCMCIA-485 cards. Refer to
Chapter 4, Using Your Serial Hardware, for more information about
transceiver modes. If you use two-wire
TXR DY
mode, FIFOs must be
enabled.
FIFO Enabled
You can use the FIFO Enabled control to enable or disable the FIFO
buffers on the serial port. FIFO buffers are present on the
16550-compatible UARTs—one for the transmitter and one for the
receiver.
Resources
Click on the Resources button to display the resource configuration
dialog box for the port. For more information on resource configuration,
