Session customization of terminal emulation application test scripts is normally not required. If session customizations are required, they must be partly performed manually. However, TrueLog Explorer can be used to insert parsing functions into test scripts.
In some cases the synchronization between replay and a host application may not work well, for example if the requested screen is not complete but the cursor position already assumes a completed screen. A recorded cursor synchronization function in the script will be satisfied with the first portion of the screen and continue executing the script out of synchronization, which may lead to replay errors. In such a case you would have to replace the recorded synchronization function(s) manually with a more suitable synchronization function in the script (for example, WebTcpipRecvPacketsUntilData or WebTelnetRecvPacketsUntilData).
