/** Takes a command string, and it's lengt writes it out to the modem
and tries to get one of the allowed responses. It writes the command
out, waits ulTimeOut millisecs for a response. If it gets one of the
expected responses it returns immediately.
If it gets an unexpected/illegal response it tries (without any
waiting) for subsequent lines to the same response. When all the
lines (if > 1) of the response lines are exhausted, if none is among the
expected responses, it writes the command again and tries again,
until ulTimeout has expired. Note that if no response is received,
the command will be written just once.
The whole above thing will be repeated upto uwRepeatCount times
if uwRepeatCount is non-zero
<<<<<NOTE:::uwRepeatCount != 0 should not be used except for local sync>>>>>
It returns when (a) one of the specified responses is received or
(b) uwRepeatCount tries have failed (each having returned an
illegal response or having returned no response in ulTimeout
millsecs) or (c) the command write failed, in which
case it returns immediately.
It flushes the modem inque before each Command Write.
Returns 0 on failure and the 1 based index of the successful
response on success.
This can be used in the following way:-
for Local Dialogs (AT, AT+FTH=? etc), set ulTimeout to a lowish
value, of the order of the transmission time of the longest
possible (erroneous or correct) line of response plus the size
of the command. eg. at 1200baud we have about 120cps = about
10ms/char. Therefore a timeout of about 500ms is more than
adequate, except for really long command lines.
for Local Sync dialogs, used to sync up with the modem which may
be in an unsure state, use the same timeout, but also a repeat
count of 2 or 3.
for remote-driven dialogs, eg. AT+FRH=xx which returns a CONNECT
after the flags have been received, and which may incur a delay
before a response (ATDT is teh same. CONNECT is issued after a
long delay & anything the DTE sends will abort the process).
For these cases the caller should supply a long timeout and
probably a repeatcount of 1, so that the
routine will timeout after one try but go on issuing teh command
as long as an error repsonse is received.
For +FRH etc, the long timeout should be T1 or T2 in teh case of
CommandRecv and ResponseRecv respectively.
