Your Helper program uses some form of the flush command after it sends a Via OS pipes, and many programming libraries buffer output data sent to pipes. Note: communication between the Server and an Helper program takes place The response lines generated with a Helper program should not be larger than 4096 bytes.

Time-out If the Helper program does not send a response within the specified period of time, the program is stopped. If the first setting symbol is $, then the rest of the setting string should be a path relative to the CommuniGate Pro application directory.
