Owen Duffy, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest server release of Ubuntu? ISO images are available from http://releases.ubuntu.com/raring/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: bios-outdated-f9 needs-upstream-testing ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/832641 Title: cdc-acm modems do not work properly using 7E1 byte format Status in “linux” package in Ubuntu: Incomplete Bug description: I have tried two apps (minicom and smsclient) with to ACM modems, and received 7E1 data does not have the parity bit stripped. I can check with STTY and it shows parenb cs7 -parodd when the port is being used in 7E1 format, but the received data has the parity bit passed through to the app. The ACM modems work fine in 8N1 mode. An ordinary RS232 modem on ttyS0 works fine with both apps using 7E1 format, and the parity bit is stripped from receive data (ie only 7 bits passed to the app). This may be a long standing problem, possibly in the CDC-ACM driver. Using oneric, server. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
