 Hello,

 Hi.

 If you want to load the puc(4) driver as a loadable module, you should
 load the sio(4) or uart(4) driver module as well.  But these drivers
 are included in the GENERIC kernel.  So you should to remove sio(4) or
 uart(4) from the kernel and load it as a loadable module.

 The other solution is to builtin the puc(4) driver to the
 kernel. i.e.:

  sio(4)  puc(4)  status
  or uart(4)
  
  module  module  work
  builtin builtin work
  builtin module  not work - current choice?
  module  builtin not work
  
  (module = loadable module, builtin = kernel builtin)

 Other modifications will not be needed for PCI multiport cards.

 I removed devices sio and uart from my kernel, loaded them as modules
 in /boot/loader.conf, and now I have 8 additional cuad? devices!

 Many thanks for your help.

 The file is /boot/device.hints. For each serial port, the
 following dataset has to be completed:

   hint.sio.N.at=isa
   hint.sio.N.port=0x3F8   ---+
   hint.sio.N.flags=0x10   ---+--- set up
   hint.sio.N.irq=4---+

 Still, I don't know how to determine the correct addresses
 and IRQs, maybe the documentation belonging to the expansion
 card can help...

Yeah, their product manual(PDF) doesn't help with this type of
information.  I'll email them and see if they can give me these data.

 If I see this correctly, each serial port should then be
 visible as a /dev/cuadN device file.

Thanks for your help.

Moxa 8-port serial multiplexor, how-to

2009-07-24 Thread Doug Poland
Hello,

I'm trying to get a Moxa Technologies C168H/PCI 8-port mux card
working in 7.2-RELEASE(i386).

I've recompiled a GENERIC kernel with

  options COM_MULTIPORT

and loaded the puc(4) module.  I don't have any new ttyd? or cuad?
devices in /dev.

After reading the handbook(26.2) and man puc(4), sio(4).  man sio(4)
talks about adding /boot/device.hints but not for my particular
hardware.  I'm at a loss on how to continue.

Suggestions, pointers, URLs welcome.
