autoit ControlSend on a putty window at a locked workstation ignores uppercase and shift key pressed characters

[jcpt]

I guys! I have developed an script that is sending command's to a putty session. Using this script remotely in a Jenkins agent works great if i have a RDP open session. When i disconnect the RDP session, the commands send to the putty session are always on lowercase and the simbols like / or _  are converted to the equivalent without the shift key pressed.

Anyone got this problem? 

cheers

Meanwhile i will keep a rdp session active always, by using this method:

for /f "skip=1 tokens=3" %%s in ('query user %USERNAME%') do (
  %windir%\System32\tscon.exe %%s /dest:console
)
