Re: uplcom(4) problem
:OK the diff (about 9k) is at
: http://rsidd.online.fr/usbserial.diff
:and the relevant files from linux 2.6.7 (around 18K zipped) are at
: http://rsidd.online.fr/usbserial_linux2.6.7.tar.bz2
:
:I think these are the only relevant files: other files in the usb
:serial directory seem to be for other devices.

:Thanks!

Hey Rahul, I got the PL2303 based usb->serial adapters but unfortunately
they appear to work perfectly. I connected up a modem via /dev/ucom0
and dialed an ISP using ppp and it works.
I looked at the linux diffs and the only thing that might effect you
is some code they have to set CRTSCTS mode. In our driver we use
index 0x41 (/usr/src/sys/dev/usbmisc/uplcom/uplcom.c), see
UPLCOM_SET_CRTSCTS which in our driver is 0x41. In the linux driver
this value seems be conditionalized to be either 0x41 or 0x61.
You could try changing the 0x41 to a 0x61 to see if it helps you, but
if it does we have tofigure out how the linux detect code works so we
can add similar code.

I'm going to spend a bit of time trying to track down the pppd cpu loop
problem while I have this thing set up.
