Bug in hex encoding for Nokia 8210

[Diego SANTA CRUZ]

Hi there,

I discovered an incompatibility between the hex encoding done by gnokii
(0.5.1) and what is required by a Nokia 8210 phone on an IrDA connection
(using AT protocol).

The phone's phonebook expects all hex numbers to be uppercase in the
+CPBW command when the HEX encoding is set (+CSCS command), but gnokii
formats them in lowercase. When the phone gets them in lowercase it
accepts the data but it gets it all garbled up.

Attached is a patch that fixes this problem by formatting hex numbers in
uppercase. As I don't have other mobile phones I cannot say if this
breaks any other phones.

BTW, why is not a saner encoding, such as 8859-1, used instead of HEX?

Best,

Diego

PS: I'm not in gnokii-users so CC me if necessary.
