Latest working kernel version: Earliest failing kernel version: Distribution: gentoo Hardware Environment: lspci - 04:06.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller PCMCIA Card - http://www.rovermate.com/site/accessories/home.nsf/descriptions/RMA19 Software Environment: module-init-tools 3.4 pcmciautils-014 udev-115 Problem Description: I try serial the modem, by means of the program minicom. At start on the modem bulb TR (terminal ready) lights up and hangs on a line of initialization. At initialization the line is entered: AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0, in the answer should be OK. Then ATZ, in answer OK. At use of the built in modem, all works. Steps to reproduce: 1) run: minicom -o 2) choose: configuration and set serial device to the /dev/ttyS0 3) choose: init.

Could you try the kernel 2.6.27?
Same result. В Вск, 26/10/2008 в 06:17 -0700, bugme-daemon@bugzilla.kernel.org пишет: > http://bugzilla.kernel.org/show_bug.cgi?id=10949 > > > > > > ------- Comment #1 from komurojun-mbn@nifty.com 2008-10-26 06:17 ------- > > > Could you try the kernel 2.6.27? > >
Well, "lspci" seems to say "Quad UART" -- so I see no surprise that there are four ports being detected, even though only two ports are connected externally. Does a newer kernel work?
