im doing a uni project and ive run into a little trouble
im writing a program in cpp (has to be cpp because of other constraints)
this program will get values from a file and depending on the values, send a high or low signal to the corresponding output pin on a serial port
i have done some research, but i cant get a solid answer on how to write from a program to a specific pin on a serial port
all i know is that i have to specify the com port (com1 or com2 etc) and the pin
any help on this would be MUCH appreciated
EDIT: im using windows xp pro, if that helps.
