    Open a serial port asynchronously with boost asio?

    Hi, does anyone know if there is a way to open a boost::asio::serial_port asynchronously? I make a series of attempts trying to open a serial port in a program I have made, but the program freezes for five to ten seconds or something when trying to open a connection. If the connection fails, it will try to open the port again (until it has succeeded) and freeze again for ten seconds or so, and so on.
    Come on, you can do it! b( ~_')

    Add thorough error checking and reporting. Any errors?
    Does it ever open successfully after a delay? Do reads and writes work as expected?

    Use the debugger to "break" during a delay and find where exactly it's occurring.

    I already have error reporting; sometimes I get timeouts from the attempts to open the port. It is the freezing of the program I want to prevent though. It's not a necessity, but it makes it feel better when you run the program.
