This methode (treat each modem command as a single one) has also the advantage, that some modem 
misbehaviours (I do not write faults :-) can be detected very easy and SOON.

I have knowledge of a lot of complainst against modem behaviour, and often the behaviour can be 
reduced to such incredible strings like AT&X*Y%ZA1B2C3D4.... which will yield finaly OK but if 
submitted one be one, there IS sometimes response ERROR or even nothing which points either to a 
wrong command or a wrong command syntax.

Often, command syntax differs slighty, depending on actually used firmware version of modem. Such 
improperties can never be localized with such large (and often senseless) commandstrings.
