Cash Drawer using com port emulater stop responding with Windows 7

I have a POS computer that is a Windows 7 64bit machine.  I have a Logic Controls USB cash drawer plugged into it.  I have installed the drivers from the Logic Control website .  The software provided by the cash drawer company is a Com port emulator.  It makes the cash drawer appear in device manager as a COM3 device.  It works beautifully after a reboot.,  but after a while it just stops popping.  I have turned off the hybrid sleep mode and every other power saving feature I can find; however, it still just stops working with out any error messages throughout the day.   My POS software calls a batch file that basically sends an ascii code to COM 3.  I suspect that maybe something is falling asleep.  I can't confirm that at all.

I went old school and added a mode statement to the cash drawer call file.   That seems to have fixed
it.
