Add a constty entry, marked 'off', with otherwise the same settings
as the console. Now when coming up in single user mode the tset in
/.profile can set the terminal type correctly.
Note: I believe constty should be 'on' and console 'off', but thats a
separate discussion

Add entries for zstty(4) serial on Qube 2700.
Also add tty0[1-3] entries to ttys(5) for com(4) at puc(4).

branches: 1.7.26;
remove ad-hok list of pty's from port tty files, and auto-generate it so
that it is consistent, and in the proper order.

Revert 'console' back to /dev/console (from /dev/constty)

Change 'console' login to use /dev/constty so that its output isn't
stolen by code that requests system messages using TIOCCONS.

Added ttyp[g-zA-Z] (bin/15594).

This should be the final part of moving to 64 PTYs by default. Added
entries for tty{r,s}{0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f} to /etc/ttys.

Thanks to Matthew Green for pointing out the need.

branches: 1.2.4;
Add comments.

NetBSD/cobalt /etc.

This should be the last piece of the move to 64 default PTYs. /etc/ttys now
has entries for 64 ptys.

Thanks to Matthew Green for pointing out the need for this.
