Hi list,

I'm trying to use a combination of two AST-4-Port ISA
serial cards with one MOXA 8-Port serial PCI card...
no luck so far. Both AST cards and the 2 onboard ports
work fine, only the MOXA PCI card ports refuse to work:

 cu -l cuaa10
 cu: open (/dev/cuaa10): Device not configured
 cu: cuaa10: Line in use

If anyone has something like this in use, please give me
a hint.

The system is freebsd 4.9-RC2 and has the following kernel
config options:

# Serial (COM) ports
device          sio0    at isa? port IO_COM1 flags 0x10 irq 4
device          sio1    at isa? port IO_COM2 irq 3

options         COM_MULTIPORT           # code for some cards with shared IRQs
#-- AST-4-Port-01
device          sio2    at isa? port 0x2a0 flags 0x501
device          sio3    at isa? port 0x2a8 flags 0x501
device          sio4    at isa? port 0x2b0 flags 0x501
device          sio5    at isa? port 0x2b8 flags 0x501 irq 5
#-- AST-4-Port-02
device          sio6    at isa? port 0x1a0 flags 0x901
device          sio7    at isa? port 0x1a8 flags 0x901
device          sio8    at isa? port 0x1b0 flags 0x901
device          sio9    at isa? port 0x1b8 flags 0x901 irq 7

#-- Moxa C168H/PCI Smartio
device          puc

The dmesg output looks like this (reduced to the sio stuff):
puc0: <Moxa Technologies, C168H/PCI> 
      port 0xb400-0xb40f,0xb800-0xb83f,0xd000-0xd07f
