DCS handling

Sending or Storing SM

When sending or storing SM in TEXT mode, only the specified <dcs>s in Table 3-46, +CSMP command definitions, will be supported. Handling will be as shown in Table 3-72.

Table 3-72shows the conversion between the <dcs> and +CSCS setting when storing SM to memory or sending SM.

Note: If SMS, requested to be read in TEXT mode, is a GSM ’7’ bit Default alphabetical encoded and contains undefined extended characters in User Data (e.g. hex base 1B07), then two septets will be converted, as two separate characters accordingly, to currently selected (+CSCS setting) character set.

Reading SM

Any <dcs> value is accepted when receiving an SM.

When reading a SM with unsupported <dcs> the message header will be passed as usual. The DATA will be output in "HEX" format.
