computer at day care controls time clock and keypass magnetic security doors. Each uses serial connector. I installed two keyspan serial/usb adapters. device manager shows keypass = com 4. timeclock = com 5 problem is software for timeclock shows only 1-4 com ports and auto detect wont see 5. I need to assign specific port to timeclock, but i don't know how. time clock must be polled mon morning.
