H01556 - COSESSION DISCONNECTS AFTER RUNNING COM2 TESTS SYMPTOM: IBM PC 300 Series 6577 and 6587 systems running CoSession for Windows may disconnect from the CoSession Viewer when the two COM2 external loopback tests in QAPlus/WIN-WIN are selected. PROBLEM ISOLATION AIDS: The failure occurs when the system is running CoSession for Windows with an asynchronous connection via COM1 and all of the COM2 tests or just the two external loopback tests in QAPlus/WIN-WIN are performed. COM2 is the built-in Infrared port on the PC 300 6577 and 6587. This port performs much like a serial port, however, the D-shell connector is female as opposed to a standard male D-shell. The external tests typically performed using a wrap connector will not work on COM2. When the tests are selected and started, the CoSession Viewer will be disconnected. FIX: Do not replace hardware. Run only the internal loopback test selections in QAPlus/WIN-WIN to test COM2. All 4 loopback test in QAPlus/WIN-WIN can be performed on COM1.
