Dual USB - to - Serial adapter

If you need a USB - to - Serial adapter, be aware that so many just didn't work that we were forced to sell the one that did. (Many work on and off, but will drive you crazy when you need to rely on them. )

S-US232B is an adapter with cable that comes with Win98/2K/XP/ME drivers on a CD-ROM. (Linux & MAC OS8/9/X are also supported). The royalty-free software drivers work like a dream. The converter cable is housed in an attractive translucent blue enclosure with a 1m USB cable. The drivers add a Windows serial Com port and requires no IRQ, DMA, or I/O port resources. Features the full set of RS-232 modem data and control signals (TxD, RxD, RTS, CTS, DSR, DTR, DCD, RI, and GND) with a DB9 male  serial port connector.
