Set command allows control of the Unstructured Supplementary Service
Data (USSD [3GPP TS 02.90/22.090]).
Parameters:
<n>
<n>
<n>
<n> - is used to disable/enable the presentation of an unsolicited result
code.
0 - disable the result code presentation in the DTA
DTA

2 - cancel an ongoing USSD session (not applicable to read command
response)

If <dcs>
<dcs>
<dcs>
<dcs> indicates that 8-bit data coding scheme is used: ME/TA
ME/TA
ME/TA
ME/TA
converts each 8-bit octet into two IRA character long hexadecimal
number; e.g. octet with integer value 42 is presented to TE as two
characters 2A (IRA 50 and 65).
<dcs>

<dcs> - 3GPP TS 3.38/23.038 Cell Broadcast Data Coding Scheme in
