Here is the story:

From a fresh install of ubuntu I use a serial to usb device. screen /dev/ttyUSB0 everything goes fine and I can interact with the device perfectly.

Then I unplug this device, plug another one (a 3g modem). Again screen /dev/ttyUSB0 and everything is fine.

But then, I plug again the first device and do the screen /dev/ttyUSB0 and everything got scrambled!

I am supposing that for whatever reason the tty parameters changed. Is there a possibility that screen store it somewhere ? How can I get back to the initial settings ?

So far I have tried:

  • rebooting
  • stty sane

Found it.

Two screen instance were actually reading /dev/ttyUSB0

Removing them all solved the issue.
