![]() Putty program can read it as COM7 nicely when interrupting the infrared matrix on the touchscreen, and shows incoming data as AxxxyyyZ, where xxx and yyy are the coordinates 1~600 and 1~800, Z is "B" when interrupting, "N" when lifting and "C" when draging, and the initial "A" is just sync. Upon connecting this device to the motherboard it enumerates USB and allocates COM7: for that on Device Manager. This motherboard I am using for test has native COM1 on BIOS, and for some reason Windows blocked COM2, 3, 4, 5, 6, 8, 9, 10. The device is a TouchScreen with an ARM controller that punch serial data at 9600,N,8,1 via a FTDI chip to connect USB to PCs. Trying to read data from a COMn: port using FreeBasic.
