rc.serial is called by rc.sysinit if the file exists. One must therefore
copy rc.serial to rc.d directory. Observing the boot log you will find
that the serial ports are not probed. Essentially rc.serial gets control
but the 'if arg for $1 being 'start' is not satisfied since it wasn't
passed. Therefore no setserial is performed.

Also as an aside the pci.h file is completely clueless about U.S. Robotics
internal pci modems. It has no vendor id and no device (1008) id. Therefore
the uart is undiscoverable and the port remains dead.

There are many problems in the area the least of which being documention
and scripts that do not work. Possibly in wrong place. Parms passed are
not valid or not passed.

I suggest you place a USR 56K Internal FaxModem in your pci slot and try
to utilize it. It is NOT a winmodem. I can communicate with it via Minicom
and doing a setserial myself. Eventually I will hack it into the operatin
system I have installed but you should fix this defect.

I need to alter this report slighty. I failed to notice the * in the IF stmt
in rc.serial. The IF stmt does run but with nothing in the 'serial.conf' file
it will do nothing. I had to prime the 'serial.conf' by doing a setserial -g
and then issuing a rc.serial with the stop value passed to get the serial.conf
file written. This is a catch 22.

I know Linux doesn't handle PnP but still there is a lot of confusion here.
Also the pci.h is still deficient. I don't see many new entries for internal
modems that have been out for some time.

You can close this problem but I basically submitted it for others to see what
the problem was. If you get way down in the depths of SERIAL HOWTO you can find
some wording on this but its flaky at best.
