Using both a serial receiver and transmitter

[Mark G. <mg...@be...>]

Hi all,

I have been using the home-brew serial receiver for quite some time with
excellent results. (Thanks to all involved in the circuit design and
developing the software!) Now I would like to add a transmitter. I
wasn't completely clear, but it sounds like I wire it to DTR and GRN on
the *same* serial port as my receiver.=20

Is that correct? Is anybody successfully using the home-brew receiver
and the simple transmitter (single diode, resistor, and IR LED) on the
same serial port?=20

I don't need much range as I can place the LED right in front of my
tuner.=20

I'd consider using one of the more complex transmitters, but I'd like to
avoid adding a power supply, and while Enrique Vidal's improved
transmitter (powered by the capacitor) looks great, I'm getting tired of
soldering! :-)

Thanks,
Mark
