Grumpy_Mike says "NO" but I just found this:
Maybe my project has some hope.
I will need to see if I can run the serial port at such a slow speed. I haven't tried that yet.
The ASR33 is actually a current loop device, but years ago I made a current loop to RS232 converter so it would run on my old PC.
Ebay has cool RS232 to TTL converters for about a 3 bucks.
This is starting to look pretty good.
I am now remembering more and more.
Does anyone remember "half duplex"?
I think a big problem will be the 110 baud. I need to find a software serial that can run real slow. At 110 baud, there is quite a bit of room for error.
