it might work if you can find the proper driver for the chip on it.This cable will not work?
Its only 4 wire in the rs232
Thats why you want something with an FTDI chip. Its a common driver. FTDI is used in lots of USB devices.
Also, be careful buying USB to RS-232 adapters. RS-232 is supposed to be +/- 13 volt, these adapters have something like an FTDI plus a MAX-232 chip converting TTL voltage up to RS-232 voltage.
I would just buy something like this for a couple bucks and wire that shit up.
Its like you have a magic box, and the magic box converts english to italian which you need for ordering pizza. But because some italians chefs are deaf, some magic boxes come with another magic box that makes the italian pizza order much louder (plus adds expressive hand gestures). If you use that kind of magic box with other italian chefs they will be offended by how loud the order is and will assume you think they are a stereotypical "loud italian", and out of spite they will burn your pizza by leaving it in the oven too long.
