Record Type 31 (1F) — TIOC Initialization

Note: While record type 31 is no longer generated because telecommunications access method (TCAM) was withdrawn from service in 2002, record type 31 remains as a placeholder.

Record type 31 is written when a MODIFY TCAM operator command is issued. This record contains the number of time-sharing buffers, buffer size, maximum number of output and input buffers allowed per terminal before OWAIT or LWAIT, OWAIT and RESTART thresholds, number of buffers reserved on the free queue, and the size of one terminal status block. OWAIT is the suspension of the program during input/output processing to the terminal because no output buffers are available. LWAIT is the locking of the terminal's keyboard because the terminal user filled all of the available input buffers.
