Hi Guillaume, Thanks for the reply. The situation is, my connection to the telco is using HTTP. For binary type of content we send it in XML format which stored in the text variable (http://host/?text=<?xml version="1.0"?><PUSH><UID>user</UID><PWD>password</PWD><SID>77700010000001</SID><TID>20003040124000000000</TID><MSISDN>1234567890</MSISDN><CONTENT TYPE=“binary”><LINE NUMBER=”1”>0B05041582000000030D030...</LINE><LINE NUMBER=”n”>0B05041582000000030D030…</LINE></CONTENT><DCS>0</DCS><UDHL>0</UDHL></PUSH>) And their server will parse the XML content.
Regards, Willy
