axwinsock control in vb.net
-
i have connected with gps device using axwinsock control in vb.net and server receiving data from terminal/device.. even server is also able to send message to terminal in binary without getting any error message..after getting response from server.. the second message from terminal should be changed but it doesn't happen..so i m not able to understand where i m wrong. is there anyone who suggest me the technical or non technical aspect of server and device/terminal communication. i explain belove the process 1)device is connected via port with my server.. 2)device send the login message to server 3)server(i) send the response to terminal according to login message(as mention in manual of device/terminal) in binary with no error but then i must have message related to the location information from terminal/device but server(i) can't get it. terminal/device still send login message... is there any conclusion of it !?
