Hmm, I think we have the answer:
Device (UAR1)
{
Name (_HID, EisaId ("PNP0501"))
Name (_UID, 0x01)
Method (_STA, 0, NotSerialized)
{
If (SOLE)
{
Return (0x00)
}
The _STA method is used to query a device's status, and a status of 0 means
that the device is disabled. I believe that this means that when you have
SOL enabled (SOLE?) that COM1 is marked inactive so the OS ignores the device.
