Ending a Line Mode Session

A line mode I/O session ends when one of the following events occurs:

• The task terminates without issuing a DC RETURN request. Programs that specify the NEXT TASK CODE parameter in a DC RETURN request can extend the line I/O session to include data transfers initiated by the next task.
• The user presses one of the following keys:
  • Clear-3270 terminals
  • Attn- 2741 terminals
  • Break- Teletype terminals
• The program issues an END LINE TERMINAL SESSION request.

  Following an END LINE TERMINAL request, DC does not automatically display lines that remain in a partially filled buffer; typically, this data is of no use to the user. However, to display the contents of a partially filled buffer before ending the line I/O session, your program can issue a WRITE LINE TO TERMINAL request that specifies the NEWPAGE option and a dummy data line (that is, one with a length of zero).
