Note
The maximum SMS length is 160 characters.
This is a GSM
standard, which allows 1120 bits, i.e. 140 bytes, per SMS. Since 7–bit
encoding is used by default, 20 characters are saved per 140 bytes
and so the resultant length is 160 characters. The GSM 03.38
character set is applied. UCS–2 16–bit encoding is used for the
characters that are not included in the ASCII standard (characters
with diacritics). In that case, the SMS contains only 70 characters.
Not supporting the UCS–2 character set, 2N SmartCOM
®
cannot process such SMS correctly and marks them as errors.
Modern GSM devices support SMS concatenating where several
standard SMS are merged into a long one. Information on each
fragment of the long SMS is written into the User Data Header (UDH)
and so no fragment may be longer than 153 chars in 7–bit encoding.
Not supporting the UDH encoding system, 2N SmartCOM

cannot process such SMS correctly and marks them as errors.

The reply format depends on the current terminal mode.

SN=<terminal_serial_number> LIP=<local_ip>FW=<terminal_fw_version>
STAT=<current_terminal_status>
