It's been a long time since I worked with serial hardware, but

something like that? If the Mac sets the other pins you might be
able to short them to the RTS/CTS pins.  I know I've done this on
special cables built to connect the 2 types of equipment.

DTR/CD aren't alternatives, they serve an entirely different purpose.

The PC software toggles the CTS signal, which the tower shorts to
RTS, so that it can tell if the tower is connected.

Since the Mac serial port doesn't have those pins, there's no way
to use the PC software under emulation.

I seem to remember seeing an add-in board which would add PC style serial ports to Macs. Now this was several years ago; it was for the NuBus; and it was rather expensive. I believe it was done so you could interface lab equipment to Macs. It may (...) (25 years ago, 17-Dec-98, to lugnet.robotics)

(...) Err, right. And if there's DTR/DCD printed on the wires it just won't play. Naughty people messing about with the assigned meanings of the pins. Whatever next? Cheers, Ben. (25 years ago, 17-Dec-98, to lugnet.robotics)

(...) Don't be so negative. All you need to do is hack the emujlator so that continuously reports those two pins shorted. Jasper (25 years ago, 17-Dec-98, to lugnet.robotics)
