Here is a fuller example. If you are getting unexpected chars then either
the port is not set correctly to match what you are talking to OR the
protocol on the other device is not what you believe it is - maybe it uses
the IRDA protocol.

Subject: Re: Serial Communication via IR
correct me if i'm wrong , and fill in any gaps i might leave out. i'm
having problems doing this redirect thingy. i open a serial port, set the
settings to 19200 etc (sersettings cmd), then after the serial port is read
as if it were to receive something thru the serial port i do the redirect
thingy. but when i go to do something like sending and receiving data its
all garbaled in strange chars. what might i be forgetting or messing up?
