[App_rpt-users] Setting Up a Remote Base w/RTCM

Check your email R. Wayne. That should do it. You don't need to use a 386,
I've successfully got the software to run on a Dual Core, running windows
98 on a second partition, which boots directly to DOS on our work
Toughbooks.

You can also get a copy of VMworks or other virtual machine and run it in
that, I've also done that and it works well. That's what I do on my i7
laptop w/ win7. I use a USB to Serial converter from FTDI
http://www.digikey.ca/product-detail/en/US232R-100-BULK/768-1074-ND/2441363.
FTDI makes one of the best USB to Serial Converts on the market.


Cheers,
Jesse
