== Overview ==
USB to RS-232 with female DE9 plug (male jackscrews) amd a DCE pinout, not normally found on a PC that would typically have a male DE9 DTE pinout. When DCE is needed though, this adapter would make a null modem (crossover) cable unnecessary. If needed a DTE pinout though, you would have to go back to using a null model cable...
== Wiring ==
This USB to RS-232 is configured as a DCE <i>not</i> a DTE, it is expecting to communicate with a DTE.
