	Alex,

	Can you please send me at least parts of the voice program
you are using? The "uninitialized value" and other Perl warnings may
in fact be originated from your code which passes some uninitialized argument
to the Modem::Vgetty module.

	On the other hand, the vgetty error apparently does not have
anything to do with the Perl module. It seems that the modem does not
support the compression from your .rmd file. You can try to create
the new welcome.rmd file with another compression method (using pvftormd,
for example). I would expect that the "vm play welcome.rmd" command would
fail with the same error.

	I am sending a carbon copy of this mail to mgetty list. You will
probably need to tell us at least the type of your modem and send more
detailed logs (set the higher loglevel in voice.conf and mgetty.conf).
