0 "REC UNREAD" received unread message (i.e. new message)
1 "REC READ" received read message
2 "STO UNSENT" stored unsent message (only applicable to SMs)

BCD numbers (or GSM default alphabet characters) are converted into cha-
racters; type of address given by <toda>
indicates that GSM 03.38 default alphabet is used and <fo>
indicates that GSM 03.40 TP-User-Data-Header-Indication is not
set: ME/TA converts GSM alphabet into current TE character set
according to rules covered in Annex A
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:
ME/TA converts each 8-bit octet into hexadecimal numbers
containing two IRA characters (e.g. octet with integer value 42 is
presented to TE as two characters 2A (IRA 50 and 65)
indicates that GSM 03.38 default alphabet is used: ME/TA converts
GSM alphabet into current TE character set according to rules
covered in Annex A
indicates that 8-bit or UCS2 data coding scheme is used: ME/TA
converts each 8-bit octet into hexadecimal numbers containing two
IRA characters
depending on the command or result code: GSM 03.38 SMS Data
Coding Scheme (default 0), or Cell Broadcast Data Coding Scheme in
integer format
converts each 8-bit octet into two IRA character long hexadecimal
numbers (e.g. octet with integer value 42 is presented to TE as two

depending on the command or result code: first octet of GSM 03.40
SMS- DELIVER, SMS-SUBMIT (default 17), SMS-STATUS-REPORT,
or SMS-COMMAND (default 2) in integer format

layer SMSC address octets are not counted in the length).
In text mode, the maximum length of an SMS depends on the used
coding scheme: It is 160 characters if the 7 bit GSM coding scheme is
used, and 140 characters according to the 8 bit GSM coding scheme.
