Subject: slcan_attach: 'close' the slcan adapter before setting a bitrate
X-Git-Url: https://rtime.felk.cvut.cz/gitweb/sojka/can-utils.git/commitdiff_plain/eb1a99f8c7e2f69b76d7edb90625e910e8326cf0

slcan_attach: 'close' the slcan adapter before setting a bitrate

As investigated by Thorsten Godau the bitrate can only be set after the
slcan adapter is in 'close' state.
