Appendix "E" - The 7 bit default alphabet of GSM phones

Your PC and your GSM phone uses two different character sets the ISO-8859-1 and the GSM 7 bit alphabet. Ozeki SMS makes a conversion automatically between the corresponging character codes in these two tables. In some cases the automatic conversion might not be fit four you needs. If you want to be sure, that a specific GSM character is used in your SMS message, you can enter it's Hex value into the messge. Before we explain how is this possible, please take a look at what characters are there in GSM.

This is the 7 bit default alphabet as specified by GSM 03.38. The corresponding ISO-8859-1 decimal codes are shown in the rightmost column. Note that the euro sign (€) is a member of the ISO-8859-15 character set.

If you wish to use any of these characters, you can do it by entering a special string into your
SMS messages. For example if you wish to add a new line character you should enter \0x0A instead pressing enter (Figure 1). Make sure you write out all the characters of this code. It is a five-letter-statement! Note that according to users' experience it also works with three backslaskes: \\\0x0A

If you wish to receive SMS messages with new line caracter, you need to set up the function in the GSM modem configuration window (Figure 2).

To send characters that require more than one byte use the following format (Figure 3)
