Many manufacturers of serial peripherals wish for a way to painlessly convert those products to USB. Using a dedicated USB microcontroller usually means extensive firmware development, as well as having to source or develop specific USB drivers for Windows '98/2000/xP and iMAC. Ready-made cables often have drivers which don't work everywhere. For older RS232 devices (and there are a lot of them: printers, barcode scanners, densitometers, and general serial products). USB-2COM cable solution with its royalty-free software drivers functions like a dream, and makes updating an old device a piece of cake - just ship the legacy device with an extra part - USB-2COM cable!

USB-2COM is available now from stock from $59 (qty 1) including free Windows '98/2000/xP, Linux and iMAC drivers from Saelig Company NY (585-425-3753; 585-425-3835fax;;
