Comment(by Treviño):

 I've seen the git commit 91d64283e87eb3223bfcdd16d68a7a20b765fd7c that
 with the others recently added should add support for USSD, btw there are
 things that I don't understand (also if I've not tested these changes in
 my hardware yet):

 - Why the CUSD command is used (in order of the ATD one) only in the
 calypso modem? I know that we're using only that in Om, but all the GSM
 modems use the CUSD command to ask USSD requests...
 - Why in dialServiceCommand() you encode the string number using the
 current codec but you don't update the relative data coding scheme (dcs)?
 I mean, actually in any case is sent something like AT+CUSD=1,"<coded-
 dialed-string>",15 while the "15" value should change according to the GSM
 03.38, isn't it? 15 stands for 1111 and so for "Language unspecified"
 according to that reference.
 An I wrong?
