Hi all,

I’m developing in Legato firmware for the FX30s to support old legacy equipment.

We used to use the FX100 w/OpenAT firmware. I have to find the Legato equivalent for the following OpenAT services:

- adl\_fcmSubscribe
- adl\_portSubscribe
- adl\_portStartSignalPolling
- wip\_TCPClientCreate
- wip\_event\_t
- wip\_write

Any help pointing me in the right direction is appreciated. Thanks!

Regards,

Eddie
