• Configure - Reassign the physical port on your device to any available Windows COM port number from 1 to

255 and give your device a user friendly Device Name. This capability is particularly helpful if you have more

than one device.

• Port Flags - Configure performance options and special functionality on a per-port basis.

Low Latency:

Normally the UART will interrupt when the receiver has been idle for 4 character times. (For example 4ms

at 9600) As long as data is being received the UART will continue to buffer them until its internal FIFO is

full (~56 bytes). This flag causes the Edgeport to poll the RX FIFO for received bytes. If any bytes are

available they will be sent to the driver without any delay.
