Re: [rhn-users] US_Robotics internal modem.

[Michel-André <michelandre videotron ca>]

do a  less /proc/pci    q  to quit
look for the US Robotic device
look a line or two after and it will tell you the I/O address it is connected
to like:
      I/O at 0xcc00 [0xccff].
       I/O at 0xd000 [0xd003].
       I/O at 0xd400 [0xd403].

take the first port < 0xcc00 >

then do: 
setserial  /dev/ttyS0
setserial  /dev/ttyS1
setserial  /dev/ttyS2
setserial  /dev/ttyS3 <------ assuming this whill give 0xcc00
setserial  /dev/ttyS4

the output will tell you which port every ttyS  is using.
The one corresponding to the 0xcc00 or whatever you found in  /proc/pci
 is the port the USR is using.

Then   minicom -s  select the [set the port....]
 select [A] to change the port, and it will show you something
like /dev/modem change it to /dev/ttyS3.   [return] [return]
after the select [A]
to go back to the original screen of minicom.

Select exit and you will get to the minicom screen. 

Do a at&v to see all the setting of  you modem

**************************************
I do not have a modem in my machine so I took another device but the example
will be something like below
**************************************
less /proc/pci

  Bus  0, device   7, function  5:
    Multimedia audio controller: VIA Technologies, Inc. VT82C686 AC97 Audio
Controller (rev 80).
      IRQ 11.
      I/O at 0xcc00 [0xccff].
      I/O at 0xd000 [0xd003].
      I/O at 0xd400 [0xd403].

[root micronator root]# setserial /dev/ttyS0
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4

[root micronator root]# setserial /dev/ttyS1
/dev/ttyS1, UART: 16550A, Port: 0x02f8, IRQ: 3

[root micronator root]# setserial /dev/ttyS2
/dev/ttyS2, UART: unknown, Port: 0x03e8, IRQ: 4

[root micronator root]# setserial /dev/ttyS3   <---------
 so for example let say it is </dev/ttyS3>
/dev/ttyS3, UART: unknown, Port: 0xcc00, IRQ: 3
