>Description:
There are several versions of the NetBSD Atari kernel.  I frequently use the "BOOT" and "ATARITT" versions on my Atari TT030.  The ATARITT verion of the kernel is necessary for me to do an install via ethernet.  On NetBSD 1.6.1, both kernels work great, however I've recently been working on getting up to NetBSD 4.0 and I've hit a blocker.  Specifically, while the BOOT kernel works just fine on 4.0, the ATARITT kernel does not.  Before displaying any text, the 4.0 ATARITT kernel displays garbled video and fails.

Note that this problem occurs with 4.0 and the daily "head" release, in this case: ftp://ftp.netbsd.org/pub/NetBSD-daily/HEAD/200810310002Z/atari/binary/kernel/netbsd-ATARITT.gz
>How-To-Repeat:
1.  Get on an ATARI TT030 with enough RAM to run NetBSD properly.
2.  Use loadbsd.ttp from TOS to boot the netbsd-BOOT kernel from:
ftp://ftp.netbsd.org/pub/NetBSD-daily/HEAD/200810310002Z/atari/binary/kernel/
3.  Observe that the kernel boots to the root filesystem prompt.
4.  Use loadbsd.ttp from TOS to boot the netbsd-ATARITT kernel from the same directory as above.
5.  Observe garbled video and the boot fails.
>Fix:
Unknown

 It turns out that this was due to a cable plugged into the serial port (null 
 modem to a PC).  Removing this allows the kernel to boot just fine.

 So please lower the severity on this PR or close it down entirely.

 Thank you!

  	I've adjusted the Synopsis and priority for this bug.

  	I wonder if the kernel might be trying to enable that serial
  	port as the serial console.

  	Could you repeat the test and run some terminal program on the
  	other end. If you are using Windows you may want to look at
  	PuTTY as an ssh and serial client:

 http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
 http://the.earth.li/~sgtatham/putty/0.60/htmldoc/Chapter3.html#using-serial

  	As a first test you may want to add the following to /etc/ttys

 ttyA0    "/usr/libexec/getty std.9600"   unknown on secure
 ttyA1    "/usr/libexec/getty std.9600"   unknown on secure

  	then boot normally and finally connect up the serial line to the
  	PC. The above change should try to run getty to permit login on
  	channel a and b on zs0. If you get a login prompt on putty then
  	you know the serial link and settings are good, then you can try
  	booting with the null-modem attached.

 May work around PR port-atari/39849
 (netbsd-ATARITT kernel fails with serial port connected)
 and some old TT030 with early revision boards.

 Log Message:
 Disable options SERCONSOLE (force serial console if DCD is detected)
 because now it's patchable by binpatch(8).

 Enabling serial console by DCD signal could be problematic
 on some earlier TT030 (with revision A board), and it's also
 annoying for users who connect an active device on the serial port
 as mentioned in PR port-atari/39849.

 XXX: Eventually serial console should be enabled by MD bootloader flags,
 XXX: but I have no idea how to build bootloader binaries for TOS.
