EHS5T ASC0 and ASC1 ports | Telit Cinterion IoT Developer Community

I would like to use RS485 and RS232 ports with Java programming for EHS5T terminal.

Is it possible to do this?

As I understand it;

ASC0 (COM0) corresponds to RS485 on GPIO,

ASC1 (COM1) corresponds to RS232 on GPIO.

When testing with Java code, I found that the COM1 port does not exist.

System.getProperty ( "microedition.commports")

I have made the following settings and can now open the COM1 port.

^ SCFG: "Gpio / mode / ASC1", "std"

^ SCFG: "Serial / Interface / Allocation", "1", "1"

(I turned off power saving mode)

When I plug the "USB/RS232 Converter" to my computer and Terminal RS232 port and test with RS232Demo project, I cannot see data communication over COM1

Where could I have done wrong?
