Can anyone suggest a simple serial terminal emulation scheme for connecting
from NetBSD/i386 to NetBSD/Sparc via a null-modem cable? Basically what I
want is this:

TCP/IP functionality
SSH
Connectivity via serial port

What I've tried so far:
I've connected a serial cable w/ null-modem adapter (see below) between Parc
port "A" & /dev/tty01 on i386 box, booted both up (Sparc has kybrd
disconnected) and started kermit and typed 'set line /dev/tty01 ; 'set speed
9600' ; 'set serial 8n1' ; 'connect' but do not get a login prompt. Am I
missing something?

OART, the null-modem pinout on my null-modem adapter doesn't seem to match
the pinout scheme given on the the Serial Port Primer:

Adapter        "Serial Port Primer Null-modem cable scheme"
     2 ----- 3                2 ----- 3
     3 ----- 2                3 ----- 2
4&5 ----- 8                4 ----- 5
                                 5 ----- 4
    6 ----- 20           6&8 ----- 20
    7 ----- 7                7 ----- 7
    8 ----- 4&5
  20 ----- 6                20 ----- 6&8

Does this discrepancy matter?
