Multithreaded drivers

[Oscar Hellström]

Hi,

Are multithreaded drivers supported on any POSIX systems these days? Or
rather, is it supported on Linux? Some of the docs say that it's only
Windows and Solaris.

Also, to be able to use driver_async() all communication with the port
must be done using port_command/2 rather than port_control/3 or
port_call/3, since the later expects a return value, am I right?

Regards
