Hoping someone on this list knows the answer to this... We have a software ap running on a notebook computer with Windows2000 system. There is a pcmcia card with a serial port stuck in to interface to external hardware. The customer has it setup to startup automatically into the application program. The problem is that about 10% of the time, the program starts up and either hasn't found the plugin card yet or it somehow gets configured wrong. Then the program runs but won't allow comms. The user must exit the program and restart it. It appears to be simply due to how windows starts up and how/when/where it recognizes the plugin card. If this is so, does anyone know how to control this behavior so the card is found 100% of the time?
