How can i detect a CDPort RJ12 connection?

Hi, i’m working on a Rocky 8.6 with a HP POS and i’m trying to attach a Standard duty cashdrawer with a RJ12 conector but i’m unable to detect via terminal the cable conected and access the cashdrawer, have tried lsusb and looked up dmesg but don’t seem to appear.

Have i got to enable this connection via bios? I would appreciate any help. Thanks in advance.
