Hi Guys,

Could CF-20 use the COM port in DOS ?

I try to edit the Saber Radio program in DOS with 4008 BOX and CF-20, but there seems to be no signal coming out the COM port, I had check the 4008 BOX and Saber Radio program is working on Desktop PC, please advice, thanks~

The COM port on that is on the keyboard is a usb type, so that will not work in DOS because of drivers. A COM port on the tablet part itself is true serial, but this a factory installed option at ordering.
