Modern operating systems (Windows 10/11) have removed the legacy porttalk.sys and direct hardware access for security reasons. This means:

Tools like EPROM programmers often communicate exclusively through parallel (LPT) ports.

There is no universal "COM LPT 17-11" driver. This number is likely a hardware ID suffix, a batch code, or a misreading of device instance data.

Native Windows drivers are generally safer than third-party installers. Ease of Use:
