How does an application like HyperTerminal work?
The application uses an anlogue modem to connect to a dsitant host.
The application uses serial com port to talk to the modem, using AT command set.
But what comes after that? There is no TCP/IP involved here, right?
Are the commands for the remote computer sent as plain text?
What is the protocol used? TELNET? rlogin? or something entirely different?
I have to develop an application which is able to connect to another host, the same way Hyperterminal does, but i have no idea how to start.
