We suspected that there's no internal clock on the adapter and the adapter uses a clock from the laptop, but FTDI support confirmed that the adapter has its own internal clock. Apparently they don't activate unless you drop DTR.

Windows' default serial behavior is different, and it worked out of the box. Ideal for legacy applications which feature UART DB9 based connectors, these modules provide a method of extending the life-cycle of these products by converting them to USB2.0 connectivity, with minimal redesign.The Increasing the delay before deactivating the driver (or even waiting until you have received it) might be a fix, if you can tolerate a long bus turn around time. http://www.nordfield.com/driver-downloads Add To Favorites This feature is only available for registered users.
