For DCE operation, the timer specifies how long to wait after the RTS
line goes high before asserting the CTS line. A timer value of zero
means that the CTS line will always be asserted (unless the radio is
attempting to throttle back data as part of normal flow control opera-
tion).
For CTS Key operation (see the
