Unable to find ZWave module?

[katyperry]

Hello,
I'm sorry to reopen this thread
I have an A64 2GB ( kickstarter ) with the zwave module in Uart on which I installed the latest version of armbian ( Armbian 24.11.1 Bookworm Minimal )
I have activated the Uart2 via armbian-config but I still can not connect via stty or MinOZW

Code:

sudo MinOZW /dev/ttyS2

ERROR: Failed to set serial port parameters
ERROR: Failed to open serial port /dev/ttyS2

Code:

sudo stty -F /dev/ttyS2 115200

Input/output error

can you help me ?
that's not my neighbor

Run ls /dev/ttyS* to see all available serial devices. The ZWave module should correspond to one of these.
