Task Type - Bug Report
Category - Packages
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Low
Priority - Very Low
Reported Version - lede-17.01

Details - If you start ser2net with configline like:

ser2net -C 4001:raw:300:/dev/ttyUSB0:57600:NONE:1STOPBIT:8DATABITS:-XONXOFF:-RTSCTS:LOCAL -u

you will get "Segmentation fault"

Starting ser2net without argument seems to be ok.


On OpenWRT 15.05.1 and earlier, there was no a problem with that commandline.
