I'm afraid this will never run in Wine/Mono.
Mono is the open source version of .NET, but apparently not completely so....
The closest thing I could find about this error is this :
If the error I encounter is related to what is being said there, SA.exe cannot run in Mono.
This is a sad thing, because a lot of people are using Linux nowadays....
Maybe the alternative can be to install Virtualbox in Linux, and install windows in a VM.
Just need to figure out how a virtual com port can be mapped onto a physical one on the host.
