There are a lot of topics on similar problems, but I don't find this one.
The System uses a Mahr Multitast indicator which sends data over a RS232 port to a Computer.
I changed the PC from an Fujitsu Siemens with an pentium 4 @ LV2011 to a Lenovo with a i5 @ LV2017, both with a integrated RS232 Port.
The new PC runs into the VISA 0xBFFF003E Error everytime it tries to read the RS232 port.
When I switched back to the old PC, it runs the first try to read in this error but works after that correctly.
The Settings on both are the same:
baudrate 4800, databits 8, parity none, stoppbits 1.0, flow control none, termination char \n.
I tried to read data at the new System through the VISA-testpanel with the same results.
I attached the I/O-Trace-files of both systems.
Any ideas on this would be greatfully received.
Regards,
Lucas
