[aprssig] Sierra wireless 881 pc card gps

You need a comm manager that will allow a comport to be a virtual com port.
May be using the wrong terms but you would tell APRS to use comm 4 let's say
if that is open then this program you set up will be told that com 23 is a
virtual port and to "patch" it over to COM 4 as if it were a real port.

I have used these lon in the past and think one is MixW Serial Port Bridge.
Also DeLorme had one I believed on their web site so you could set up their
USB GPS units to feed several virtual ports and feed several programs with
the same GPS data.

A few days ago I asked if this card worked with APRS. It does have a gps
inside and I can see the nema data on com23. I have yet to figure out
how to get aprs to look at the com port. When I tell it 23 at 4800b, the
the program dies.
Any ideas?
