Wine and USB serial ports

Post by Boxadog » Tue Mar 31, 2020 9:52 am

Hi I'm very new to Wine and have tried to get a piece of Amateur Radio software (Win4icom) working in wine on MAC High Sierra. The Win4icom software communicates with an Amateur Radio transceiver via USB. The USB port requires a driver (Silicon Labs USB driver) which creates 4 virtual serial ports. These are listed in /dev as,
tty.SLAB_USBtoUART
tty.SLAB_USBtoUART1
cu.SLAB_USBtoUART
cu.SLAB_USBtoUART1

The driver and USB connection using the Silicon Labs driver work perfectly with native OSX software.

To try and get Win4icom to work with wine I have created 4 entries in the wine registry in hkey_local_machine/software/wine/ports as follows,
com4 /dev/tty.SLAB_USBtoUART
com5 /dev/tty.SLAB_USBtoUART1
com6 /dev/cu.SLAB_USBtoUART
com7 /dev/cu.SLAB_USBtoUART1

The 4 com ports are showing in the software (before entering the registry data they were blank) but when i try to connect to the transceiver, Win4icom hangs along with wine. I have to force closure of wine to clear it.

I have surely missed something here due to my lack of knowledge. Is it something to do with linking ports to the driver? Can anyone help please?
