[Elecraft] Is anyone using a Hardware Data Switch instead of LPBridge?

[George Danner]

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!

While LP Bridge does serve the purpose I was wondering if anyone was usinga 
pure hardware solution to share the K3's serial port across applications.
If so how are you doing it?
