[Bug 556854] Re: serial ports malfunction on lucid

[Eric Firing]

Additional testing using python to open the port and read or write: When
opening the port is successful, the light on the Keyspan changes from
blinking to solid.  This occurs on jaunty, but not on lucid, or on
Knoppix 6.2.1 (kernel 2.6.32.6) or on Fedora 12 (kernel 2.6.31.5).
Contrary to what I thought I remembered from testing a few weeks ago, I
am finding that Karmic also does not work at all with these 1-port
Keyspans.  Kernel 2.6.31-30.  Karmic and Lucid both show the peculiar
behavior of starting the port with settings -icanon and 57600 baud, but
Fedora and Knoppix do not.
