a data/fax call, the comma digit is ignored, and all other
digits before and after the comma are considered
addressing information (phone number).
The plus <+> digit: Indicates that the international access
code exists in the number.
semicolon (;) When given after <number string>, a voice call is
originated to the given address, otherwise a data call is
originated.

ATDP, ATDT, AT*D, <T>, <P> and <*> are ignored. The command is handled as ATD.
The control of supplementary services through the Dial command is not supported as these are controlled through
the specific supplementary service commands (CCFC, CLCK, and so on.)
Initiating a GPRS connection is done through ATD*99#, as described in “D*99, Request GPRS Service "D"” on
