Can I delete COM ports in Wine?

farthing · 07-27-2023, 06:29 AM

I have installed Wine v6.03 under Mint v21.2 and it has created 33 COM ports in dosdevices.

When I open my Windows application I have to select a COM port from a huge list.

I will never need more than four ports and would like to know how to remove the rest.

I tried defining the ones I want in regedit but it doesn't suppress the ones I don't want.

Is there a fix for this please?

I have 4 COM ports listed, which are links to /dev/tty entries. I've just deleted one of them, using the file manager, and Wine still seems to run happily. Try moving the excess ones to the waste-basket and see what happens.

Hello David

With no devices connected to the PC Wine creates COM1 to COM32 which are linked to /dev/ttyS0 to /dev/ttyS31. If I delete them from dosdevices wine recreates them. If I set each one to a null value in regedit then Wine creates new ones starting at COM33.

Why do I have so many if you only have four?

Yes, the one I deleted has come back. If you run the registry editor and go to local machine - hardware - device maps, you can find them listed under serialcomm. You could try deleting there and see if that works.

Nice idea but still no luck. I deleted the unwanted listings in serialcomm and also dosdevices but they all reappeared moments later.
