sending a four character sequence prompt:
(IRA 13, 10, 62, 32)
After this prompt text can be entered; the entered text should be
formatted as follows:
- if current (see +CSMP) indicates that GSM03.38 default
alphabet is used and current (see +CSMP) indicates that GSM
03.40 TP-User-Data-Header-Indication is not set, then ME/TA
converts the entered text into GSM alphabet, according to GSM
07.05, Annex A; backspace can be used to delete last character
and carriage returns can be used; after every entered by the
user the sequence is sent to
the TE.
- if current (see +CSMP) indicates that 8-bit or UCS2 data
coding scheme is used or current (see +CSMP) indicates that
GSM 03.40 TP-User-Data-Header-Indication is set, the entered text
should consist of two IRA character long hexadecimal numbers
which ME/TA converts into 8-bit octet (e.g. the ‘asterisk’ will be
entered as 2A (IRA50 and IRA65) and this will be converted to an
octet with integer value 0x2A)
Note: the DCD signal shall be in ON state while text is entered.

by echo command E
