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));

•Sending can be cancelled by giving <ESC> character (IRA 27).

•<ctrl-Z> (IRA 26) must be used to indicate the ending of the message body.
