@section fmc-fdelay-term
The command can be used to activate or deactivate the 50 ohm
termination resistor. In addition to the @t{-i} or @t{-d}
arguments, mandatory if more than one board is found on the
host system, the command receives one mandatory argument, either
@t{1} (activate termination) or @t{0} (deactivate termination).
