When connecting to a Linux device using a serial port there may be times where that connection becomes stuck open and thus will not provide sane output to the TTY port. This issue can be resolved by killing the PID (Process ID) and letting the serial port process restart.
The serial port connection should be configured in inittab which will allow you to specify various configuration options as well as respawning the process. So when you specify respawn the process will automatically restart if it is no longer running as will be the case if you kill the process off. The inittab entry will look similar to one of the two below examples.
We wrote an article recently about restoring your iPhone to the original settings by restoring the firmware on the iPhone and then backing up your settings. Sometimes simply resetting the iPhone settings will resolve conflicts or functionality you may have lost because of a setting that was changed. There may also be cases where you need to reset the iPhone network settings which can be completed from the same location. Follow the directions below to factory default the settings on your iPhone or to factory default the network settings only.
There are various scenarios where you may need to restore your iPhone to the original settings. After restoring to the original settings you can then restore your iPhone from a backup but the problem with this may be the initial conflict could have been caused either by a setting or an application installed on the iPhone. Recently I reset my iPhone to its original settings because I thought it would resolve an issue I was having with Visual Voicemail however it did not end up resolving my issue because after restoring from the backup the conflict that caused Visual Voicemail to not work was restored and so Visual Voicemail stopped working again. I will explain the details behind that in another post but below I describe the process of first restoring the original settings to the iPhone followed by restoring everything else from a backup.
With Trillian you may from time to time get connection admin messages that describe some sort of problem. At times these error messages or warning messages will pop up when Trillian starts and you may be in a hurry to just close them out so you can get on with working. The problem with this is that if the issue needs to be resolved you may not know how to retrieve these messages. One such error could be similar to my last post that described an error with the Yahoo Messenger plugin so in this case the error message came from the Yahoo Admin.
