Handles for services are retrieved from the service manager port, "srv:". Services are an abstraction of ports, they operate the same way except regular ports can have their handles retrieved directly from a [[SVC]](svcConnectToPort).

The Register command registers a process with the service-manager, which includes registering the serviceaccesscontrol for the process which normally originates from the [[NCCH/Extended_Header|exheader]].

−Prior to to [[7.0.0-13]], the commands listed for "srv:" were also accessible under this port with the same command-headers. Starting with [[7.0.0-13]], the commandIDs for these "srv:pm" commands were changed. "srv:pm" was originally vulnerable, this was fixed with [[7.0.0-13]], see [[3DS_exploits|here]]. Originally any process could use "srv:pm", however starting with [[7.0.0-13]] this was restricted to a maximum of 1 session. The only system title which uses "srv:pm" is the [[Process_Manager_Services|Process Manager]].
