SHDSL Modem Configuration - OneAccess 1423

Hello,

I have SHDSL modems, brand OneAccess, model 1423.
There are two types of configuration:
- through a graphical interface by connecting to the modem's address.
However, I can't do this; it requires a version of Java. After wasting quite a bit of time setting up an old XP machine with an outdated Java version, it still doesn't work.

- through the console port.
I found some documentation, but I can't understand how to configure anything.

I need to change the operating mode to point-to-point
Define who is central or remote
Set an IP address
Define in WanInterface the trunk mode to SinglePair
Change laninterface1 to Dot1QSwitching

I'm navigating through the modem using the SET command to configure… But I can't seem to configure an attribute.

Do you have simplified documentation that would allow me to modify these parameters?

Thank you for your help.
