Data transfer between GPRS modem and Remote server

hi,
i know its not a new thing here but i am facing little problem with GPRS. i am using SIM300 modem and here is the log of hyperterminal

now i cant figure out whats the problem and why is it not connecting?
any hlp and suggestions are welcomed

It may be becasue ou're trying to connect on port 21, which is the FTP port. Google won't allow you to connect on that port - try it on a PC (usning Telnet) and you'll receive a timeout error.

well i tried on 80, 8080, 9201 and alot more....

can it be because i am using google rather than its IP?? i mean can this be factor? (i wasn't able to try that one, will try it tomorrow)

well i tried putting in the server IP instead of domain name....at first it showed "connect ok", but when i send data to server...it shows "send ok"...but no data received at server.
i am trying to send data over testbed.somee.com which has a shared IP, does that effect??
