Faith,
Another means of communicating with a serial device is to use an IP-RS232 converter such as those sold by gridconnect - http://www.gridconnect.com/serial.html. They have a range of devices; using the IP-RS232 device, you can put these anywhere on a network and communicate with them as if they were a serial port on your PC. Let me know if you need any further details.

Hello Folks It looks like I can send a sound or wav file to a set of PC speakers, this is in the docs. Any advice, hints or gotchas on using this syntax in a form in an 'On Exit EEP'? SET VAR vPlay = (GETVAL('PlayAndWait','c:\windows\media\tada.wav')) Will play sound/wave file and waits for the sound to finish before continue to a next command. This could be a long time if the sound file is long. You would want this if, for instance, you're writing an answering machine aplication in R:BASE for Windows. Also, is it possible to do/send any or all of these from an RBASE 7.6 application? 1) flash the screen with a color for a certain duration? 2) send a command to a USB connected device ( in my case a stacklight) , (when we find one... in case the RS232 to USB adapters won't work with the devices below or ... in the event that RBASE 7.6 can send control commands through a USB port but not through an RS232 port) 3) send a command to an RS232 connected stacklight? http://www.wolfautomation.com/Product.aspx?ProductID=21036
