strange characters killing terminal

This is a pretty important problem for me and I'd appreciate any help I
can get.
I'm using a Redhat 5.1 box to capture report printouts from a legacy
system over its serial port. So far everything has gone fine, but the
report we're printing now seems to have lots of characters in it that my
terminal sessions don't like. If I try to "tail" or "head" the file, I
get a dash and one of those solid rectangle characters, and my login
hangs and must be killed; can't even send a break.
I can view the file in less, but it looks pretty crazy. Regular, just
crazy. I'm not sure how well this will come across via e-mail, but the
excerpt below _should_ be mostly in English, and it obviously isn't:
HESC-^@ESCr^@ESCP
^RESCFESC
HESC-^@ESCr^@ESCP
^RESCFESCHESC-^@ESCr^@ESC2ESCP
614785 DON P D.O. 02/20/1997 0 0 15
0.00 ^
All of the "ESC" sequences and several of the ^ and @ symbols are
highlighted, in case it matters.
Other than refusing to display, everything seems to be going okay; the
file is steadily growing on the disk, it's just ugly. None of our other
reports have done this (same machines, same data set, but a different
type of report).
Is this likely to be a terminal emulation issue? The legacy end of the
chain thinks that it's printing to a dot matrix printer, again in case
it matters.
