Recently I wanted to use the serial port to communicate with a gsm phone. To my suprise this did not work and odd errors were reported - like phone not connected when the phone could tell me there was a connection.

I have checked the BIOS settings which are irq 4 and 3F8 for port 1 and irq 3 and 2F8 for port 2. This should be correct but still FreeBSD reports otherwise. I suspect this has something to do with acpi(?). Could anyone give me hints on how to debug and correct this problem? -- Sven Esbjerg
