Connecting to IMS using SLU-1 devices

Secondary Logical Unit (SLU-1) devices can connect to IMS using a telephone data set.

Prepare the SLU-1 device for communication before attempting to log on. See the SLU-1 operator's guide for the proper switch settings.

You should log on to terminals that are connected with a switched line using the procedure below. Log on to terminals connected through a nonswitched line using the same procedure, but start with step 2.

Procedure

  1. Establish connection with the computer through a telephone data set.
  2. Press the Sys Req key. The Proceed light should go on.
  3. Enter the logon message.
    For example, to log on to an IMS system named IMSA:
    • Enter: LOGON applid (IMSA)
    • Response: DFS3650I SESSION STATUS

If you want host-initiated logon for a SLU-1 Data Communication System, you must leave the terminal in a line-to-console job. To prepare the SLU-1 terminal for host-initiated logon:

  1. Press the Start Job key. For a 3774 or 3775, also press the S key.
  2. Press the Line key.
  3. Press the Console key.
  4. Press the EOM (end of message) key.
