Hi Pete
thank you for your timely response.
Win 8.1 may support serial ports - Com but they have removed any reference in Device Mgr or Computer management.
have not entered a port into ini because I cannot find any reference to any specific name.
I have tried using Com 1, 2, 3, etc. within the GPSout but nothing comes back... The program I am working with is FSXFlight and it works perfectly with my Win 7 box... The GPSout for win 7 shows a Com3 connection.
I am also trying to get in touch with the developer of the App ( who has posted to this forum) to see if he might have run into 8.1 issues. Continue to scour all the likely forums to see if anyone else might have a workaround.
thanks again
Greg
