rt_com tests

["Torti, Richard A" <Richard.Torti@MW.Boeing.com>]

I am having some troubles with the rt_com package.  Specifically, the
testcomrtai module does not seem to work correctly.  I am able to load
rt_com.o and testcomrtai.o with success messages in dmesg, but nothing is
being received across the serial line.  Furthermore,  running 'setserial'
after the modules are running does not reflect any differences
'rt_com_setup' should have made.  (I'm not sure whether it should or not.)

By the way, I can send and receive using my serial ports without the rt_com
modules.

I am using rt_com-0.5.4 and rtai-22.2.4.

Thanks,
