[TriLUG] stty: 'standard input': Inappropriate ioctl for device

[Alan Sterger via TriLUG]

Hi List,

Attempting to scp a file from my NAS to an Azure resource is returning:
stty: 'standard input': Inappropriate ioctl for device

scp [sanitized] command:
scp /mnt/test/get-ddl.sql oracle at foobar:/home/oracle

I've toggled .ssh/config file ControlMaster setting from auto to no with 
no change.

Any suggestion to make scp upload work?
