Get two programs to talk to eachother on two separate LANs (send messages?)
Posted on 2009-07-16
I need to send a message from my application on LAN 1 to my application on LAN 2, which simply needs to reply back Yes or No.
This is in deepest darkest Africa so I can only assume there will be some basic internet connectivity using maybe GPRS / 3G technology, or something like that, but probably not ADSL.
I need to know what components I need to use in Delphi, what protocol I would be using, would I be targeting a port, and some source code wouldn't hurt :)
Thank-you in advance.
