Harry, Years ago we used 8 devices controlled from one PC com port on one RS-232 data link. All of the devices bridged the receive line and were wire or'd for transmit. The devices were polled by the PC and only allowed to transmit when polled. This worked well with no conflicts for many years. So it is possible to use one RS232 port for multiple devices -but- the devices must be made to play nice in all circumstances and have special hardware interfaces. My best memory is we spent about 20 man hours developing the hardware solution and another 100 hours writing & debugging software. BTW this was in DOS days!

If so how are you doing it? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
