Jason, Some PCs are getting good service with agrmodem+agrserial. Sometimes problems like your > [ Â236.833883] Modules linked in: agrserial agrmodem coretemp etc arise with particular motherboards. They may sometimes be alleviated by unloading unnecessary drivers before loading the modem drivers. Detach unnecessary external hardware first. $ lsmod starting from the top of the displayed list, test with: $ sudo modprobe -r driverName When you have removed all you can, then try loading the modem drivers and checking the port. We do recommend wvdialconf for testing, but first you will have to set a symbolic link $ sudo ln -s /dev/ttyAGS3 /dev/ttySAGR as wvdialconf only tests ports with /dev/ttyS* designations, and USB ports. Do send further help messages to the List, not me directly. Also you should send the ModemData.txt output from scanModem MarvS MarvS On Wed, Dec 15, 2010 at 10:19 PM, Jason Stahls <jason@xxxxxxxxxxxxx> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > I've been trying to get the modem in my Acer Aspire 5315 laptop working > and I've made it to the point where I can load agrmodem and agrserial > and get /dev/ttyAGRS3 to come up.
