[comp.sys.mac.hardware] how to multiplex serial port?

jonathan@cs.pitt.edu (Jonathan Eunice) (03/26/91)

I am constantly switching the cable for my Mac Plus serial port from a modem
to a LapLink cable, and back, and forth, and back, and...well you get the
picture.  I'm also considering a serial printer, which will really make
things unpleasant.  Is there any way to multiplex the serial port?  I'd 
be happy to use the devices one-at-a-time, if only I could get some hardware
gizmo that would let them all be physically plugged in simultaneously.
Any ideas?
