For troubleshooting we need the vmx-file and the vmware.log
But honestly I would suggest to find a workaround that does not require a working parallel port.
I tried to troubleshoot some similar problems and had to give up without success.
I was hoping that this would be fixed by 15.1.1, yet is is apparently going to remain broken until it has visibility that people actually have needs involving virtualized older systems. Up through vmware workstation 12.5, I have been able to use the LPT: port in the virtual machine, now it doesn't even show up, regardless of the adapter.
There is one serial/parallel adapter that should work well, as it has the features in Windows 10 that are appropriate, as well as a driver that lists it properly.
My use case is interlnk/intersvr from dos, as well as filelink.exe from dr-dos, as well as laplink parallel connection, as well as windows direct parallel transfer. All of these require
parallel port LPT1: as opposed to printer port LPT:
It shows up in VMware workstation 15 as nothing, and in vmware 12.5 it shows up, but does not actually function. In workstation 12.5, I could still use a dell legacy dock, but those are in the future no longer a possibility with any new hardware, so I really need this function to work again.
Does anyone have an idea how to add this port in vmware 15.1.1, it is clear that adding the port will not work if workstation cannot see the port.
If I open an older machine, created in past times, the port is visible, but does not function. If I convert such machines, or upgrade them, the port is no longer there.
Here is an older example of what I expect to see in workstation that no longer works.
Anyone have an idea?
