EMS PDU specification

[Ext User(arcx33)]

Hi,

I was wondering if anyone could help me with this. I have been looking
for a complete list of what codes are used in the User-Data-Header in
EMS messages.

So far I have been able to send some test messages and get the codes
for font size, weight, slant, colour, and underline. I can continue
like this to get codes for Pictures and melodies but I have noticed
that there are some gaps in the codes I am using that my phones do not
seem to be able to produce.

So my question is, does anybody know where I can get a list of these
codes?

Thanks,

The use of UDH (of which EMS capability is a subset) is a big
field, and constantly expanding. The primary source is GSM
03.40, and its GSM/UMTS replacement 3GPP 23.040. You can
download these specifications from either www.etsi.org or
www.3gpp.org - look for recent versions.
