And there is a serial/usb dongle that will allow you to still usr serial devices. At least I have one that I may auction off sometime in the future. :-)
This solves the issue for some uses. We use high-end GPS receivers that, in addition to the serial data, pulse the CTS line on the serial port at the top of every UTC second. This is required for any serious time synchronization. Sadly, the USB converters cannot duplicate this signal so it arrives as a hardware interrupt. BTW, newer Linux kernels even have a special device driver (pps) to time tag such signals accurately. Sadly, USB need not apply.
