Bitrate between 9600 and 115200?
Maybe try "coolterm" instead of putty?
If you connect the DB 9 to your computer, then do not connect TX and RX to Z-Uno UART (only 3V3 and GND) but connect the converter's RX to the converter's TX, does the terminal echo what you type?

Re: Z-UNO + RS232
We were typing at the same time.. UNO cannot do less than 9600 bps.
There is another topic about bit-banging... Give me a second...

Re: Z-UNO + RS232
Your problem finds confirmation (but no solution) here:
https://forum.z-wave.me/viewtopic.php?f=3427&t=26015
This guy tried or tries to do "parity" by bit-banging and finds out... The Z-Uno runs faster or slower depending on its opwer supply:

This guys says he "ordered an SPI to UART bridge" but he does not mention if it works...

Re: Z-UNO + RS232
For a shame, adding another bridge is too complex for me.
A change in HW UART to support 2400 baud would be perfect for me, even if I had to buy a new HW version of Z-UNO.
Regarding Software Serial, I know that library from Arduino, but it's unportable, as it uses too much of ARK-specific code.

We plan to make SoftwareUART soon. Please stay tuned

Re: Z-UNO + RS232
Hi guys,
I tried that new SoftwareSerial library with 2400baud and it works GREAT
Thanks!
