TCP connections are always bidirectional, so no separate transmitter and receiver settings
are needed.

Selecting the check box will enable the streaming of UART data over TCP
using a client/server connection. The server accepts requests from a
specific client, or any host if not specified.

UART settings section.
[0...255] data words. Will have the next packet sent when the line has
remained idle for longer than the timeout.
[0...255] data words. The maximum latency of the data channel is
controlled by forcing a packet to be sent when the first data word of the
packet was received longer ago than the number of word times set here.
Normally, the devices at the two extremes of a bus are terminated, while
intermediate devices are not. Therefore: RS-422, always enable (being
point-to-point); RS-485, enable only for the first and last module
connected to the bus configuration.
If biasing is needed (RS-485), it should be enabled on at least 1 module
on the bus. RS-422 does not require biasing.
