Disconnecting the Host Link

When the host receives the response to the DACTPU command, it returns a command to Personal Communications such as the Set Disconnect Response Mode (SDRM) command when using SDLC protocol. The SSCP can also disconnect immediately at any time by sending the same command to Personal Communications, which ends all sessions. When sessions are ended in this manner, all SLUs that were active earlier receive a loss-of-contact indication.
