Restrictions for SMS texts
The internal GSM character set does not match the usual ASCII
character set of PCs in all positions.
Therefore, the following restrictions must be observed for SMS
texts:
¾ Never use the character 0x00h.
¾ Permitted text characters in SMS messages are only letters
(without umlauts), digits, punctuation marks, brackets, un-
derscore, %, & *.
¾ 8-bit characters (e.g. umlauts) and $ @ { } [ ] ^ ° ` ´ are not
supported.
¾ In e-mail addresses, the character @ must be replaced by the
character * . KPN in the Netherlands requires replacement by
the character!
¾ If you do not enter the message text via the entry mask of
the HSComm software, you must replace the underscore by
the letter 0x11h.
