The link layers that run under emulators should set a bit in the LinkModuleInfo liFlags to indicate they are running within an emulator.
Applications can then use this bit. E.g. SAFE2 needs to run in PASV mode when under emulation.
I suggest bit 14 is used for this.
Needs to be documented within LinkModuleInfo
Bit 14 has been used by Ewen.
Documentation has been updated in 20 July 2013 revision.
