That cannot be correct, because:

console "/usr/libexec/getty std.9600"   vt220   off secure
ttyC0   "/usr/libexec/getty std.9600"   vt220   on  secure
ttyC1   "/usr/libexec/getty std.9600"   vt220   on  secure
ttyC2   "/usr/libexec/getty std.9600"   vt220   on  secure
ttyC3   "/usr/libexec/getty std.9600"   vt220   on  secure
ttyC4   "/usr/libexec/getty std.9600"   vt220   off secure
ttyC5   "/usr/libexec/getty std.9600"   vt220   on  secure
ttyC6   "/usr/libexec/getty std.9600"   vt220   off secure
ttyC7   "/usr/libexec/getty std.9600"   vt220   off secure
ttyC8   "/usr/libexec/getty std.9600"   vt220   off secure
ttyC9   "/usr/libexec/getty std.9600"   vt220   off secure
ttyCa   "/usr/libexec/getty std.9600"   vt220   off secure
ttyCb   "/usr/libexec/getty std.9600"   vt220   off secure


We don't declare pccon.  We are never going to declare our ttys as
pccon.  It is a non-standard name.

So trying to achieve "pccon", whatever that is... what is the goal???
