Sorry I don't know your name.
With the flags you indicate wich sio have the master port.
the flags have 1 word or 2 bytes or 16 bits.
if the flags is 0x0B05 (in Hex) is tha same that 0b0000101100000101 (in Bin)
the minor byte (0x05 or 0b00000101) has tree bits that means something
^ ^^^
127 421
the first (127) if enable (set to 1) it's enable diagnostics in probe
the second (4) if enable means that the card isn't an AST/4 compatible
IRQ control register.
the third (2) if enable that means that the FIFO is going to be disable
the fourth (1) if enable means that is going to share an IRQ
In this case 0x05 means: we don't have a diagnostic in probe, and
that the card hasn't a AST/4 compatible IRQ control register and the
FIFO is enable with a IRQ shared.
THe high byte (0x0B or 0b00001011) all his bits mean somthing
the firts (0b00001011) if set means that the port is goin to generate
^ a call out.
the second(0b00001011) if set means the device is going to be locked, the
^ CTS RTS are locked. (i ma not sure how work this
bit.)
the tird (0b00001011) if set means that the port is goin to be
^ initializaded (i don't know how)
the rest (0b00001011) is a number that represent in wich sio is the
^^^^^ master port.
0b01011 is 11 in decimal, that means that sio11 is the master port.
try this options:
options "COM_MULTIPORT"
device sio4 at isa? port 2e0 tty flags 0x0905
device sio5 at isa? port 2e8 tty flags 0x0905
device sio6 at isa? port 2f0 tty flags 0x0905
device sio7 at isa? port 2f8 tty flags 0x0905
device sio8 at isa? port 3e8 tty flags 0x0905
device sio9 at isa? port 3f8 tty flags 0x0905 irq 4 vector siointr
with the flags 0x0905 you are indicating tha the sio9 at the 3f8 port is
the master port.
the vector siointr is the ISR (Interrup Service Rutine) you where
talking about.
that was what i understand in the sio page.
if some one has an other version let us kwon.
i hope, i could help you.
