TCPIP delay notable, resume RC transceiver

The delay due to TCPIP communication could potentially exceed 20ms which
is the width of a PWM signal.  Therefore, future PWM reading will have
to run in its own time frame and TCPIP communication cannot squeeze in
between readings.

Resumed experimenting with the RC transceiver project.  I am trying to
figure out how to read from the transmitter and reliably control a
servo.  Redirecting input signals to output pins does not mimic direct
servo connection to the receiver.
