Hi, I have a TC-800 8 port serial card from ByteRunner (www.byterunner.com). It is a 16550-based card which supports shared interrupts, and has an IRQ-status register "for UNIX compatibility and faster IRQ response". The ByteRunner web site has a link to the serial ports section of the FreeBSD handbook (2.1.0 version!!!) rather than explicit instructions for installing with FreeBSD. I already have AST/4 clones running happily on my system. I configured a kernel with COM_MULTIPORT and 8 ports tied together as for the AST/4. I added the "verbose" bit to the flags. None of the sio devices was recognised, and the probe failed at "test 3", which looks like the IRQ test in sio.c. I also tried a Bocaboard-8 kernel configuration, again to no avail. There are two modes for the card - standard and "Unix". The Unix mode has an 8 byte chunk of memory mapped for and "Interrupt vector", usually, but not always, located immediately after the port 7 address. Sio(4) man page does not seem to handle this other than by saying "only AST/4 control registers are handled." Has anyone managed to get one of these cards working under FreeBSD? At A$21 per port, they would be very nice to get going.
