If the TerminalDriverBindingStart() function is succeeding then the device path is likely correct. TerminalConInTimerHandler() is an event handler that is registered here: https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Universal/Console/TerminalDxe/Terminal.c#L958 The gBS->CreateEvent associates the function with the event. The gBS->SetTimer() sets the period of the callback on the event. The Timer services is part of UEFI and provided by the DxeCore. The DxeCore depends on the Timer Architectural Protocol to provide a timer tick. https://github.com/tianocore/edk2/blob/master/MdeModulePkg/Core/Dxe/DxeMain/DxeProtocolNotify.c#L31 If the Timer Tick is registered the gTimer global will be non NULL and setup to callback in to the DXE Core periodically.
