Since I know it works with hyperterminal or executing "telnet 164.256.1.1 2000", I was wondering if this can be done with QT.
Then what I want to know is to send ASCII commands once the connection is established, as well as to receive them. Can it be possible?
I think you can open the "telnet 164.256.1.1" with QProcess, then you can write and read to / from it - to send commands use write method. You can receive them when waiting for readyRead signal and then calling one of read methods: read, readLine, getChar, readAllStandardOutput / readAllStandardError.
