Using telnet in a C Program
c, networking, telnet
Solution
You are looking for sockets. This is a comprehensive guide to socket programming in C. Telnet is also a well defined protocol, although I don't know if this robot would use telnet or not (it's extra processing overhead for a protocol that wouldn't have much added benefit for a robot control program). Telnet is covered in detail by RFC 854
Problem
I am working on a robot automation project and I have run into a road block. To control the robot, one needs to connect with it wirelessly via telnet and send commands through the tcp/ip protocol. (ex. The 'Mabc' command moves it forward based on the left wheel speed (a), the right wheel speed (b) and time (c)). What I am trying to do is do some calculations in a C program and then send a message to the robot based on the value of the calculation. How can send commands via tcp/ip protocol in a C program? Thanks! Erik
