USB232 smart adapter cable lets PC users add an additional serial port for RS-232 connections using USB. It provides an external plug-and-play port for convenient connection of cell phones, digital cameras, modems and ISDN terminals. Just plug the serial device into the cable and the cable into the USB port. Automatic handshake is supported. No IRQs are required. This smart cable transmits up to 230 kbps with a 96 byte buffer for upstream and downstream data flow. It also has handy LED indication of RX and TX data which is great for diagnostic purposes.
