For those less interested in Windows and more focused on Linux or Pi versions of ham radio software, please take a look at https://getpat.io/ .
The latest release is on github at https://github.com/la5nta/pat/releases Latest is v0.12.1.
It is a command-line / Web Gui version of a Winlink mail client that now has the ability to use all of the forms available in Winlink.
It can operate over telnet to check basic operations and day to day use, but also has interfaces into ARDOP, AX25, PACTOR, Winmor and also has access to a serial TNC.
I have tried this on Windows but do not have a Linux machine around to try out.
