Greetings everybody,
I have been developing a C++ Win. Forms application in VS2010 to acquire data from an external device continuously.
In the tutorial of the device the followings are given about commucating with device through RS-232.
The external device has a communication format of 38400 baud, 8 data bits, no parity, and 1 stop bit. And communication
link is controlled by the protocol request ENQ (05h) to determine if the receiver is available to acquire data. The
response is either ACK (06h) or NAK (15h).
But, in .NET SerialPort control, following handshaking methods are the options:
XOnXOff
RequestToSend
RequestToSendXOnXOff
I have searched the internet to find a tutorial explaning the relation between these handshaking methods and the communication signals, ENQ, ACK and NAK. But, unfortunately, I have not found anything useful, yet. Consequently, I would like to ask you if you could send me a link of tutorial or some source to take a look at.
Thanks in advance
