[hpsdr] optimizing my PC for TCP/IP to Hermes/Metix?

[George Byrkit]

Ken,
My greater fear is that some hams will purchase the Microsoft 'Surface' tablet, especially
the ARM version, and wonder why PowerSDR and KISS won't work there.  If the ARM version,
it would require that the apps be 'Metro' apps, which they won't be for (quite) a while.
Or worse, that they'd want it to work with Ozy/Magister when the drivers just don't exist.
I think that the Intel version of the 'Surface' may also require a 'Metro' app, being a
tablet.  So out-of-luck there as well if that's the case.

On a laptop or desktop, with the 'real' Windows 8, you should be able to run PowerSDR and
KISS.  We will do what we have to do to ensure that those regular apps work as 'regular
apps'.  If anyone wants to make Metro apps of them, we have a job for you!  Hours are
long, and pay is low.  Satisfaction can be high.  Countless bugs may be reported, and help
may be minimal.  It's the 'Henney Penney' thing...

73,
George K9TRV

Thank you George. Yes I misunderstood that Hermann was using a 100BT
LAN. I have a Gigabit switch here and my mITX (Atom 330) says it
is connecting at that high speed. But my poor old dual-core Dell
needs a new Gigabit LAN PCI card!

I thank you very much for your comments about Win-8. I simply will not
worry about it. My fear was that Hams would purchase the new Hermes and
then at Christmas time they would purchase a new i5 or i7 PC and it 
would be delivered with Win-8 installed on it :-(

I am approaching this from a "Customer Support Tech" point of view :-)
and I wanted to have a clear understanding about what utilities and
potential optimizations we can offer to our happy and excited new
owners :-)

many thanks George,
73 Ken
