network support, <scts> is returned. Values can be used to identify
message upon unsolicited delivery status report result code. If sending
fails in a network or an ME error, final result code +CMS ERROR:
<err> is returned. This command is abortable.
• The entered text (GSM 03.40 TP-Data-Unit) is sent to address <da>
and all current settings (refer Set Text Mode Parameters +CSMP and
Service Centre Address +CSCA) are used to construct the actual
PDU in the ME/TA.
• The TA shall send a four character sequence
<CR><LF><greater_than><space> (IRA 13, 10, 62, 32) after the
command line is terminated with <CR>; after that text can be
entered from the TE to the ME/TA.
• The DCD signal is in the ON state as text is entered.
• The echoing of entered characters back from the TA is controlled by
V.25ter echo command E.
• The entered text should be formatted as follows:
if <dcs> (set with +CSMP) indicates that GSM 03.38 default
alphabet is used and <fo> indicates that GSM 03.40 TP-User-
Data-Header-Indication is not set:
if TE character set other than “HEX” (refer command Select
TE Character Set +CSCS in TS 07.07): ME/TA converts the
entered text into GSM alphabet according to rules of Annex
A; backspace can be used to delete last character and
carriage returns can be used (previously mentioned four
character sequence shall be sent to the TE after every
carriage return entered by the user);
if TE character set is “HEX”: the entered text should consist
of two IRA character long hexadecimal numbers which
ME/TA converts to 7-bit characters of GSM alphabet (e.g.
17 (IRA 49 and 55) will be converted to character Π (GSM
23));
if <dcs> indicates that 8-bit or UCS2 data coding scheme is used
or <fo> 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. two characters 2A (IRA 50 and 65) will be
converted to an octet with integer value 42).
• Sending can be cancelled by giving <ESC> character (IRA 27).
