Question: I have an NEC 6000 series laptop running Windows NT 4.0 and I can't get my modem working. Answer: NEC 6000 series laptops running Windows NT 4.0 require that all on board serial devices are enabled (9-pin serial, infra red, and any internal modems) before a PCMCIA serial device will function. If you are not sure how to enable your serial devices in the BIOS, please contact NEC.
