Subject: Re: [boost] How to access COM ports

Thank you, Now my example is half done. I can open the COM port and write on it. But still I am tweaking with the response of COM port. When I write to COM port data goes to attached device that works perfectly but then device returns the response. Response comes in the same stream, so I am reading the response from the same stream. The problem is that the response comes sometimes after 3 seconds, some times it comes after 5 seconds. If I read immediately then it reads the same data I send to COM port. Then I used threading and I force my program to sleep 3 or 5 seconds till the response comes and then read the data. Now it reads response correctly. But it does not read correctly every time. Now I am going to try two options 1. Do finer coding 2. Change the device. Can anyone tell me how to add example in boost docs example. Because there are very few examples for asio; specially on serial port. When my example will be complete I want to add it to BOOST documentation. And yes! my portability issue is also solved. I do not need to use winsock or socket.h etc. Because Boost is itself portable, if I use Boost's library for networking then it will be automatically portable. Only we need to find out which library can serve our purpose.

There's nothing in boost to support COM/serial > ports yet. Actually, yes. Boost.Asio does support serial ports: But I've never used this feature, so I can't really help. -- gpd _______________________________________________ Unsubscribe & other changes: Add more friends to your messenger and enjoy!
