Hope some of you RS-232 GURU's out their can help me with this small problem.

I am trying to get Aegis Draw to talk to an Apple 4 Color/Pen Plotter.

According to Apple, this plotter supports hardware handshaking only.

	Current configuration is as follows


		1-------------------------1
		2-------------------------3
		3-------------------------2
		5-------------------------20
	       20-------------------------5
		7-------------------------7

Pin 20 is the DTE line which according to Apple goes to the "Computer"

I am assuming that this only requires it to be hooked up to pin 5 CTS on the
Amiga.  I assumed wrong.  No hardware handshaking transpires.

Aegis Draw uses 'COPY' to copy its ASCII plot file to port 'prt:' using
the 'Custom'/'Generic' printer driver.

I guess my question is... Have I wired the RS-232 Cable correctly.  Does
the Amiga sence a toggling signal on pin 5 for the equivalent of hardware
xon/xoff.  Does the Custom/Generic printer driver cause COPY to sence hardware
handshaking.  Where am I going wrong!!

Any help will be greatly appreciated.
