Some Huawei mobile broadband sticks utilizing the NCM protocol expose the control channel as a cdc-wdm device node instead of a virtual TTY. This device node does not support the terminal ioctls. This patch adds a check whether the provided device is a TTY or not and does not attempt to use the terminal ioctls if they are not supported. v2: reduce diffstat by simplifying code a little Signed-off-by: Matti Laakso <malaakso@elisanet.fi> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@44054 3c298f89-4303-0410-b956-a3cf2f4a3e73 |
