	I have more serial devices than I have serial ports on my
computer. Sparing you the gory details, let's just say that I *cannot*
just buy a serial board and plug it into an unused slot. What I really
need is a smart T-switch: on one side it would plug into my computer's
serial port, on the other side two or more serial devices would plug into
*it*. Based on, say, an escape code from the computer, the switch would
connect one of the devices to the computer's serial port. Does such a
thing exist?

	Let me point out that I do *not* want the reverse of this setup --
i.e., a "printer sharer", which connects two computers to one serial
device. 

	Go ahead, make my day -- tell me where I can find such a beast!:
