hi,
l am currently trying to connect the serial port (COM1) of a computer to an 8051 Microcontroller. l've figured out that l have to use a Visual Basic timer in order to detect a packet that comes from the micrcontroller, but the question is why exactly do I need to use a timer for the serial port (COM1)?
please help
