This USB to RS-232 is mostly configured as a DCE <i>not</i> a DTE, it is expecting to communicate with a DTE. <i>Mostly</i> because pins 1 and 9 have the wrong direction, they are not outputs, whether or not they are actually inputs needs to be verified...

== 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.
