\item[initRS232] tries to close and reopen the RS232 connection. This is
useful for the automatic fixing of communication problems encountered.
\item[initRS232WithFlags] the same as initRS232, but with flags. flags = 1:
do not block on connect (use initRS232Finished to check success).
flags=2: wait 1000 ms after last close or restart (workaround for a bug
in Lantronix terminal server). flags=3: both options. flags=0: no opitons.
\item[initRS232Finished] returns 0 when connect in progress, 1 when finished,
FAILEDCONNECT on failure.
\item[closeRS232] closes a network connection but does not delete the datastructure.
\item[createRS232] creates a new rs232 data structure with all
parameters at default values. The connection is NOT opened.
