Kaplan), the consumer electronic stuff place, sells an RS-232 BSR X-10 controller for $19.95 + $4.00 shipping (note that it's not in their latest catalog, but they do still sell them). With this and a BSR X-10 appliance module for about $15, you can control the light/noisemaker(s) of your choice (up to 15 amps worth) from an RS232 serial port. If you order the IBM PC version, it comes with standard RS232 25 pin connector. You need to be able to send 8-bit characters (it uses all 8 bits) and it only speaks at 600 baud!?! I don't know how BSR X-10 stuff works in commercial/industrial environments and it's kind of "comsumerish" to put in a product you are going to sell, but it works great for me at home. pete peterson {decvax,linus,wjh12,mit-eddie,masscomp}!genrad!rep
