I'm by no means an expert but I'm using Asio for serial port communication (on Windows only) for a few years now without any issues. I'm mostly controling projectors but also connected some light and trigger control boards. As long as the (virtual) COM device is available I didn't have any problems with Asio. Also I don't know of any other library (inside or outside Boost) besides the OS specific ones, but I have to admit I didn't look around much, since I already had Asio based network code and the Asio serial communication worked flawlessly.

Hi, this example is really useful, I created a class to talk to a serial modem. However, the 'talking ' usually does not work! I am sending an AT\r to the modem and wait for an OK. In most of the cases the code waits and waits and waits and nothing is happening. Any ideas what to check? Or what mailing list/forum to ask this question?

Hello!

I have already used this class to implement communication with serial devices in a professional environment. There's actually not much to say about it, since its use is so easy and straightforward.

Regards,

Andreas

I forgot to mention, that I've been using this on Windows as well as (embedded) Linux platforms. Am using it for controlling radio devices.

Regards

Hello! First of all I'd make sure that the modem actually responds. I had problems with my USB-Serial Adapter that sometimes I wasn't able to transmit/receive any data over it, reopening the port or replugging it to the computer helped there. You can do this i.e. by using a terminal application (Hyperterminal, Minicom, TeraTerm) and try to talk to the modem there. When you're sure it works, try your application. Also (even if it doesn't say so in the docs) try to send "AT\r\n" if you don't receive anything with just "AT\r"; I guess this depends on the modem firmware...
