Daniel O'Callaghan scribbled this message on Jun 23: please only post to one list, I got duplicates... > 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". well.. every port has an irq status register... now the question is if it has something similar to the AST/4 irq status register, that reports which ports have an irq pending.. > 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. there is a bit that tells FreeBSD to ignore the results of test3... > I also tried a Bocaboard-8 kernel configuration, again to no avail. see above.. > 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 hun?? how is memory mapped after io ports?? > page does not seem to handle this other than by saying "only AST/4 > control registers are handled." actually.. AST/4 irq status registers aren't even supported yet... I'm about finished with support 'em... > Has anyone managed to get one of these cards working under FreeBSD? > At A$21 per port, they would be very nice to get going. nope, but I have some 4port Computone ValuePort V4 that I'm working with... there are other problems with the COM_MULTIPORT define than just not supporting the irq register... ttyl.. -- John-Mark Gurney Modem/FAX: +1 541 683 6954 Cu Networking Live in Peace, destroy Micro$oft, support free software, run FreeBSD
