Well, in this case I was using a "printer" cable, I guess.  So my dilemma
returns.  It seems odd to me that I could do a zterm to zterm connection but that I
couldn't do a

Ah, then it seems I was using a printer cable.  So the dilemma returns,
and I present my original question:

I'm trying to get a serial console or boot echo to work from my Powerbook
duo 230 to a 6100/66 running zterm.  I can get a direct connection
going between the two machines if I run zterm on both, but attempting
to turn on Boot echo or serial console results in no output to the other
machine.

My Configuration:

Duo 230, 12/122, 120 = 110 root/usr + 12 swap, Apple MiniDock, external
15", extended keyboard and mouse


Here's what I've done:

The 6100 is running zterm, 9600 N81, with or w/o Xon/Xoff
The Duo:
   some of the kernel/binary combinations attempted:
        a: 1.2 binaries, Daishi kernel
        b: -current (mar ~3) binaries, Daishi kernel
        c: 1.2 binaries, GENERIC25 kernel
        d: -current, GENERIC 25 kernel
   other modifications:
        e: configurations a,b,d with getty running on either or
                both tty01,tty00
   booter modifications:
	f: either or both serial ports set to raw, serial boot echo
        g: either or both serial ports set to raw, serial console

When booting to serial console, the boot gets to the "So I sayz to 
him...", then nothing happens (I suspect this is where it should start
being sent to the serial console?).  Otherwise, with the boot echo on,
nothing happens, although sometimes when using the 1.2 binaries and either
kernel, if I hit return or send a break from the 6100, the NetBSD box will
hang (at a prompt, during boot, whichever).  I'm not sure if this happens with the
-current stuff, I'm not sure that I've tried this. 

Questions I have/potential problems:

1. Perhaps the modem and printer ports are not tty01 or tty00
   (I suspect this is the case for the Daishi kernel, but I'm not sure how to figure this out)
        a. Solution: try serial console without Dock 
	b. Play around in the kernel (clues on how to do this?)


Thanks,
