Serial UART Terminal misconfiguration creates apparent hang at (stack) about punyforth HOT 6 CLOSED

Hey there, i'm experiencing the same problem (using an ESP-01 module with a recent punyforth clone from yesterday).

The flashing procedure works, so does booting, but it doesn't print the "Punyforth ready." message, and seems to hang after displaying "(stack)".

I'm using minicom instead at 115200 baud, 8N1, through a PL2303 based USB-to-serial adapter.

The ESP seems to function otherwise, as i can see a WiFi AP appearing with a SSID corresponding with my module's MAC address.

My next step will likely be retesting the PL2303 (which is working bidirectionally since i was able to both flash and receive the boot messages), and observing the serial communication closer to see if i'm missing something.

See you all back here!

Hi, can you try this out with coolterm, using the settings from the readme.md? I remember having some problems with screen. Probably it never worked with screen or screen should be configured differently.

Hello, i had similar problem with TeraTerm/punyforth neither with TeraTerm/other kind of forth.
If i remember correctly punyforth is not doing a reset/init on the UART port before using it and i suspect this is the reason why some of us get troubles.

Thanks for the tip @GerardSontag, I'll investigate this.

Switched to Windows (Virtualbox based on Free Windows 10 90-day 'Edge' tester from Microsoft). That's because Coolterm is only available as a 32-bit application on Linux, and it was looking like a world of pain to install multiarch and a whole set of i386 desktop libs just for Coolterm.

Coolterm (on windows) does indeed function against the flashed punyforth on NodeMCU-M (ESP8285) following my flashing with --flashmode dout

I was then able to prove that miniterm could also connect and behave as expected if I avoided my usual --raw flag (which disables line mode), and added a new --echo flag. Connecting like this was successful from CMD.exe after installing Python3 into windows (adding it to the path). For Pip instructions try... https://vgkits.org/blog/pip3-howto/

pip3 install pyserial
python -m serial.tools.miniterm --echo COM3 115200

And now also proven to work back on Linux...

To install miniterm (after installing pip3)...

pip3 install pyserial

Then run it like...

python3 -m serial.tools.miniterm --echo /dev/ttyUSB0 115200
