How to redirect serial port:





One more thing that makes FlexiHub a really great COM port redirector is the speed of connections. The app’s traffic compression feature allows transmitting serial data significantly faster. Users find this especially helpful when interacting with certain types of devices that originally communicate data in an uncompressed format.
On top of that, if two users are logged into the same account, they can start communicating with comments and reactions via a convenient FlexiChat - one of the latest improvements to the program. FlexiChat is available in the Windows version of the app.
