Use PCO to identify the workstation

If you have a PCO capable terminal emulator (e.g. ClientAccess/400) WindowsEnabler/400 can use a different method to identify the workstation.

The first time when a WindowsEnabler/400 request is executed in an interactive job, this job uses PCO to send a message to the WindowsEnabler/400 program on the PC (2). This message is sent through the PCO support of the terminal emulator (1). The WindowsEnabler/400 program on the PC then sends a message to the WindowsEnabler/400 program that is running in the interactive job, specifying the PC ID (3). The WindowsEnabler/400 program stores this ID in a data area in QTEMP for later reference. From now on all WindowsEnabler/400 requests will use this ID. The PCO method is used only once. The requests now follow the normal route through (4) and (5).
