pci modem,setserial, and 2.6 kernel

[matt zagrabelny <mzagrabe@d.umn.edu>]

hello,

i am having difficulties installing an pci modem with setserial and the
2.6 kernel.

it seems that the name(s) of the serial modules have changed from 2.2.x,
2.4.x to the 2.6.x series. what used to be "serial" is now "8250" and
"8250-pci", etc.

the (relevant) contents of /etc/modutils/setserial looks like:
alias /dev/tts          serial
alias /dev/tts/0        serial
alias /dev/tts/1        serial
alias /dev/tts/2        serial
alias /dev/tts/3        serial
post-install serial /etc/init.d/setserial modload > /dev/null 2>
/dev/null
pre-remove serial /etc/init.d/setserial modsave  > /dev/null 2>
/dev/null

so my questions are:

1) setserial has autodetected the modem on /dev/ttyS3. i believe i need
to make some sort of alias from that device to the 8250-pci module. is
this correct?

2) the aliases listed above seem wrong. shouldnt /dev/tts/0  be
/dev/ttyS0 ? this question is probably just academic, but i am curious.

3) if i do a "modprobe 8250-pci" the modules loads without error. is
there a way to see what device that module is loaded for?

thanks for the help
