Hi friends. I am using Qt4.3 with VS2005. I am working on a Data Acqusition System. I am using Qt to develop the Application. I need to acquire the data of the selected channels from the Embedded System and Plot Graphs in the Application. For which i need to implement a Protocol. I have the following -

Format byte -- Service ID -- Data bytes -- Check Sum

Format Byte is the size of Service ID and Data byte. ,example- 0X03
Service ID defines which Channel I have selected. ,example - 0XC1
Data Byte is the parameters i have selected in the Channel.
Check Sum is the size of Format Byte and Service ID ,example- 0XC4

I have to send all this on a serial port to the embedded system which has all these defined so it is going to select the required Channel and send the data back to the Application.
Hey this is the first time i am doing this i have done a some searching on Google but i am not sure about how to implement this. ?? I don't have any one at my work to help me out with this.
