I plugged the serial lcd display to the usb-serial converter (USB232A) using a female to female adapter which is plugged into a usb port which is connected to a motherboard usb connector. I have set the lcd display to a speed to 9600 and the COM3 serial port (the usb-serial adapter) is set at 9600 speed, Data Bits = 8, Parity = none, stop-bits = 1, and flow-control = none. I tried using your wintest.exe program and all that is displaying on the lcd screen when I try something all I get is a blinking command prompt and the program freezes. If I just use a regular serial cable and plug it into a normal serial port, everything works fine. Am I doing something wrong? I want to use the lcd display through a usb port.
