1 serial port = 1 device. Why would you want a pass through on something that doesn't support more than one device? If you don't want to plug and unplug devices, get yourself one of those old switcher boxes.
Personally I don't see it as a big deal to unplug the modem if I need to use the serial port for something else. I think in all the years of using an Amiga I have never had anything plugged into the serial port except a modem and occasionally a NULL modem cable. Parallel port, yes as I have a sound digitizer and a printer.
What other device do you use with your serial port?
