how do make so picomite accept serial data from python over usb

this program works if data is incoming on the gpio pins

' Slave PicoMite (ONTVANGER) - Minimalistische UART test met correcte SETPIN syntax
' Ontvangt een bericht via COM1 (UART0) op GP0 (TX) en GP1 (RX)

' **BELANGRIJK: Definieer de UART pinnen met SETPIN volgens de nu werkende syntax**
' SETPIN RX_PIN, TX_PIN, COM_CHANNEL_STRING
SetPin GP1,GP0,com1

' Open de COM1 poort op 9600 baud.
Open "COM1:9600" As #1

Print "Slave PicoMite: Start. Wachten op data van Master (op GP1 (RX))."
Print "Verbind Teraterm met deze PicoMite's COM poort voor output."

Dim RX_MSG$ ' Variabele om het ontvangen bericht in op te slaan

Do
' Controleer of er data is in de input buffer van COM1.
If Lof(1) > 0 Then
' Lees een volledige regel (tot een newline) vanaf de UART.
Line Input #1, RX_MSG$

' Print het ontvangen bericht naar de console van de Slave PicoMite.
Print "Ontvangen: " + RX_MSG$

End If
If RX_MSG$ = "Zon" Then
Print "ZON"
End If

If RX_MSG$ = "water" Then
Print "WATER"
End If

Pause 10 ' Korte pauze om de processor te ontlasten
Loop

' MMBasic sluit de poort automatisch bij een nieuw programma of stroomuitval.

G'day Tenij,
The console / USB serial connection on the PicoMite is #0, so you need to point at this for any (USB) serial data i/o

Also LOF() is the transmit data buffer, LOC() is the receive buffer.

I find the following the best starting point, it will echo anything received back to sender, always my goto as a first test

'program to test USB Serial comms

Do
If Loc(0)>0 Then
Print Inkey$;
EndIf
Loop

End

Hope this helps,
Regards,
Lyle.
