Hi,

Steps to reproduce oops :

1. insert PL2303 serial converter
2. connect to it with cu (cu -l /dev/ttyUSB0 -s 115200)
3. take out PL2303 converter from the box
4. hit Enter in CU

Such behaviour notices since 2.6.29.x. 2.6.28 was correct when disconnecting
PL2303 device - cu simply print that line is dsconnected. Can supply any
additional info.

TIA
