Ahhhhh...thank you. I actually saw a post that Alan Renouf had Working with VM Devices in PowerCLI | VMware PowerCLI Blog - VMware Blogs and he had some functions for removing devices like serial and parallel ports, but I didn't know why they would not show up if I added the line to the .vmx file. Do you know if there is a way to prevent the adding of those devices beforehand?
Regardless, that is useful information, and I appreciate it.
