I am developing a .net program that needs to communicate with a magnetic card reader/writer. it has a DLL but i couldnt find its functions and the producer company told me that i have to use only with serial port commands. In its manual, there is some commands that has been explained not clear enough ! I tried to use them but i couldn't get any response for non of commands. Does any body has experience with card reader devices ?! Is there any handshaking or initialization i need to set ?!

My card reader model is : Skankyo 6940

As said Dennis asking a vendor and reading its docmentation is more productice and most accurate way you can approach to work with the library .

Alternatively you may think of using: DUMPBIN.EXE utility, to dump all export functions of that (presumably C) dll. I repeat,in this way is much harder then reading a documentation, but, yes, you can also find some "hidden gems".

Hope this helps.
