Yes, there's a trick ;-( Here's how it works: There's three methods for finding serial ports that apply to rx2600 w/ECI card. First, we parse the HCDP table. Second, we search the ACPI namespace for serial ports. Third, we walk the PCI busses looking for serial ports. The two built-in serial ports are in the ACPI namespace, the ECI card actually contains a PCI bus where we find the serial ports. Firmware determines which port is listed in the HCDP table according to which Console Input & Console Output devices were listed first. Unfortunately, you can't tell which one was selected first, so the safe thing to do is make sure only one is listed. > Which version of firmware do you have installed?

In the instance you quote here, ttyS3 would be the mirrored port. ttyS4 and ttyS5 are the local and remote sessions respectively. Of course, it should be: ttyS0 mirrored console ttyS1 serial A ttyS2 serial B ttyS3 UPS ttyS4 local session ttyS5 remote session once you fix your ConIn/ConOut settings. -- "It's not Hollywood.
