Open Cash Drawer
This piece of code will pop open an MMF ED 2000 Cash Register. It sends the ascii value of A down com port 1. I put this code on planetsource code cause I had a hard time finding out how to do this. I tried the MSComm object and had a lot of difficulty with it. Hope this helps all the coders out there.
