A variety of information on disks, video, drivers, IRQs and port addresses was provided. ). National Instrument software version 1.5 for the RS485 PCMCIA card locks up the MSD. That was fixed with version 1.6. Unfortunately, loading version 1.6 changes the hardware configuration (com ports A serial communications port on a PC. See COM1 and serial port. com port - communications port ) on the MSD from the required 2-wire setting to 4-wire. 1. Right click on My Computer. 2. Select Manage. 3. Click on Device Manager. 4.
