playback - IBM x3270 trace file playback tool playback [ -p port ] trace_file playback opens a trace file (presumably created by the x3270 "Trace Data Stream" facility) and plays the host data it contains back over a socket to processes that connect to it. It also displays the data produced by the process in response.

Once connected to a process, playback is used interactively. Keyboard commands control the flow of data from the file to the socket. These commands are:

s Send one line of data.

r Send one record of data (send data until the TELNET EOR sequence is reached).

q Exit playback.

d Disconnect the current socket and wait for another connection.

Suppose you wanted to play back a trace file called /usr/tmp/x3trc.12345. In one window, run: playback /usr/tmp/x3trc.12345

In another window, start x3270 with the command: x3270 localhost 4001

playback will announce the connection.

Thereafter, the s and r commands will send data from the file to x3270.
