Hello,
When I gave the latest version of the editor joe a try (you can find it
at ftp.std.com:src/editors/joe1.0.11.tar.Z), I stumbled across the following
two oddities:
1. Using either one of the console drivers, joe seems to behave incorrect.
Try the following:
a. Ctrl-K h
b. Choose any help screen you want
c. Hit PGDN a couple of times.
This results in the dissapearance of the help screen, something that
did not happen when I tried it on my computer at work which was connected
to a pyramid and ran kermit as the vt220 emulator.
Two questions:
a. Can anybody out there duplicate my results ?
b. Is this a bug in joe or in NetBSD ?
2. I use pcvt as my console driver. This means that my /etc/ttys contains
the following fragment:
console "/usr/libexec/getty Pc" pcvt off secure
#vga "/usr/libexec/getty Pc" pcvt on secure
ttyv0 "/usr/libexec/getty Pc" pcvt on secure
ttyv1 "/usr/libexec/getty Pc" pcvt on secure
ttyv2 "/usr/libexec/getty Pc" pcvt on secure
If I try to run a kernel with the pccons console driver using the /etc/ttys
that has ttyv[0-7] in it I get the following panic when ttyflags is started
from /etc/rc:
vm_fault (f8664b00, 0, 3, 0) -> 1
fatal page fault in supervisor mode
trap type 6 code 2 eip f818690b cs f8660088 eflags 10202 cr2 bs cpl 0
Everything will work fine when I comment out ttyv[1-7] in /etc/ttys.
