EHS5T Terminal RS485 minimum baud rate | Telit Cinterion IoT Developer Community

Hello,
When I try to open RS485 port of EHS5T terminal with 300 baud, 7 data bits, 1 stop bit, Even parity, I get error. (The reason I use 300 baud is that the IEC62056-21 protocol starts communicating at this baud rate).
I have read 1200 bauds of the lowest baudrate supported in the documents.
I think this only applies to terminals.
Normally, the UART of the EHS5 module can be switched to 300 baud.
Is there a chance that I can open the RS485 port of the EHS5T with 300 baud?
Thank you.
Hello,
The module itself has only RS232 interfaces. For RS485 there is an additional chip used in the terminal wich is connected to module's ASC0 RS232 interface. So if the documentation states that the lowest baudrate is 1200 bauds, I'm afraid that 300 bauds won't work.
