[hpsdr] COM Spliters

[Mike F]

I use com0com to connect from powersdr to my logging program (log4om). 
I use psdr cat2 to connect to other applications such as fldigi and 
wsjt.  However I would like to be able to have all of the programs talk 
to each other, and this is suppose to be doable using a com spliter 
program.  I have chosen to do this using hub4com, the companion program 
to com0com.  I set this up following the process that should produce 
three bidirectionally enabled com ports.  Using three instances of putty 
I have verified that this is working as planned.  However if I connect 
powersdr in place of one of the puttys.  The two remaining puttys still 
communicate fine, but psdr does not join them.  Without changing psdr 
cat, it works fine directly connected to an application.

PSDR is v3.3.6.
