Any other ways to detect COM ports beside probing and ACPI?

Post by devsau »

Currently, I have found that the legacy_devices flag in the acpi boot_arch table does not always seem to be accurate. In say 90% of machines, it is.. but sometimes not.

Is there any other real way to detect these? I were wondering if maybe there is a pci sub-class code for PCI to ISA bridges like there is for the 8259 and 8254.

thank you :D
