includes drivers that create additional COMn devices within Windows that
when a program opens one of those "virtual COM ports", NMEA data is
magically there. I suspect that's not what you mean by the same term.
More likely, UI-View's feature is just what was originally request, a
new port type in APRSISCE/32 that can be configured as any one of my
three (currently) physical ports (TCP/IP, Bluetooth, and COMn) such that
wherever APRSISCE/32 is getting it's GPS data from, NMEA data is sent
out to the new port type in a fashion similar to a downstream APRS-IS
Now, if an enterprising person were to install a third-party "virtual
COM port" driver, and subsequently configure one of those truly virtual
ports in APRSISCE/32 to be an NMEA feed port, you'd have some
inside-the-PC NMEA sharing capability between concurrently executing
I'm all interested to learn just what UI-View's "virtual COM port"
really does, but I suspect it simply opens a COMn port and pumps NMEA
data out via that port and any "virtualization" is up to other software.
