Strange console message

[Brian May <bam@snoopy.apana.org.au>]

Hello,

Occasionally when I come to log on, I see the following message:

snoopy login: invalid code, row=0, col=1728, file offset=e1, skip to eol

Anyone know where this message is coming from?

This message doesn't seem to be generated by syslog. I am not sure how
it found its way to tty1 (the active console at the time).

Today I received a FAX (probably advertisement :-( ), via the default
mgetty setup. Perhaps this generated the message, maybe when encoding
the fax into a format suitable for mailing? ie
from /etc/mgetty/new_fax?

This computer is mainly slink.
