Re: Serial port programming.

["William J. Thomsa" <wjthomas@wcvt.com>]

If you look in the Win32 help that comes with ObjectAda (not the AdaWin32
help, but the orig one from MS), and look up Communications that will take
you to a section that explains all of the functions associated with serial
communications in Win32.

The next thing you want to look for is an article (on msdn.microsoft.com)
entitled "Serial Communications in Win32". This white paper tells you all
about using the above mentioned functions using Overlapped IO which allows
you to set up event, receive and transmit tasks to service the ports.

The whole subject can get quite complex but if you stick with it you can
acheive a nice abstraction for a "port" (using taksking) that will not spend
most of its time polling the ports for traffic.
