As i am using Sierra Wireless GSM GPS module HL-6528-G2.8V, in which my module is taking GPS frames and after filling it in my packet format ,it is sending this packet format on TCP towards server.
I am using TCP connect, Packet send, TCP disconnect in this fashion cycle continuous with interval of 1 minute.
Problem is only 14 packets are getting sent. From datasheet i ahev come to know that I have not defined Hardware data flow using AT&K3 command. When i send AT&K3 command then module hang up there or stops there.

I don't know why this is happening? Please any one can help me in this...

Thank you in advanced.
