Hello Jerome,

Generally, I would not include an attachment. However, this is a
tiny zip and includes the test source, build scripts and the compiled version.

Well... I found that your ansitest.com still works with the FreeDOS 1.3
kernel + nansi.sys 4.0d.  (I.e. there was no regression between FreeDOS
1.0 and 1.3.)

I took a FreeDOS 1.3 "floppy edition" boot disk image, and doctored it
so that it loads nansi.sys on startup and does not start the installer,
then ran it under QEMU.  ansitest.com says "ANSI supported".

(I will try to enclose a floppy disk image once I manage to pare it down
to a small enough size...)

Are you using devload.com to load the nansi.sys driver?  If so, this
might explain the failure.  I found that if I use devload.com --- rather
than load the driver through fdconfig.sys --- then for some reason
nansi.sys's input handling routines are not triggered, and there is no
ESC [ y ; x R response.  This would mean there is an issue in devload.com.

Hello Tom,

have YOU thought about using your favorite DEBUG tool to chase down
this issue?

Diagnosing this problem with debug.com turns out to be trickier than
expected, since it involves tracing the innards of int 0x21 that
debug.com also uses for its I/O...

Thank you!
