it's right :(
i try next config:
>>>show config
[...skip...]
ISA
Slot Device Name Type Enabled BaseAddr IRQ DMA
0
0 MOUSE Embedded Yes 60 12
1 KBD Embedded Yes 60 1
2 COM1 Embedded Yes 3f8 4
3 COM2 Embedded No 2f8 3
4 LPT1 Embedded Yes 3bc 7
5 FLOPPY Embedded Yes 3f0 6 2
2
0 COM4 Singleport Yes 2e8 3
in kernel:
device sio0 at isa? port IO_COM1 irq 4 flags 0x10
#device sio1 at isa? port IO_COM2 irq 3 #flags 0x50
device sio3 at isa? port IO_COM4 irq 3
in dmesg:
sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 16550A, console
sio0: interrupting at ISA irq 4
sio3: configured irq 3 not in bitmap of probed irqs 0
sio3 at port 0x2e8-0x2ef irq 3 on isa0
sio3: type 16450
sio3: interrupting at ISA irq 3
no worked :((((
so, can i try to run serial port under FreeBSD in pooling mode? :)
