Serial Port Hangs after xxxx Time

An old VB6 application runs under Win XP which communicates with a controller via COM port 2. The application always stops working after a certain period of time. There was simply no more data sent. The application was also unable to close the Com Port. We tried 6.1.30 and 6.1.28 without success. Now it has been running for several days thanks to version 5.2.44

It is certainly not a problem for the VB6 application, the error could also be reproduced with the HTERM program
