It's probably easiest to think about this from under the hood. In both cases, the IR port is simply sending a series of electrical pulses (on and off) With IR there are a prescribed series of pulses at a certain frequency that translate into on/off flashes that are interpreted as binary (ne: hexidecmal) numbers. With serial, the pulses are set to frequencies that a standard rs232 port understands. but it's still just binary/hex values being inturpreted on the other end.
the IR port is one-way. So also is the port when set to serial. you can send but not receive.
Anyone know the difference between the Serial mode and Data mode for IR?
From memory the three modes are as follows:
IR: Usual mode for controlling equipment that has an IR receiver using an IR bud.
Serial: *Not* one way TTL level serial. Rather, an inverted IR pulse train for controlling some equipment with "wired IR" ports.
Data: This *is* one way TTL level serial which will control most devices with an RS232 or TTL serial port.
My memory is hazy on the "Serial" mode - I'm sure someone will correct me if I'm wrong.
