Oh, please.  This question is asked about once a week on this list.  For
example, the USR Courier series is very good.  Multitechs have good and
bad firmware versions.  Same for ZyXEL.  ELSA is ok, but not as good as
USR.

Huh?  Interesting model number :-)

Weird.  Upgrading the USR Courier series is really easy (get about
200kbyte, run an .EXE file under DOS or upload a .XMD file with X-Modem
and you're done)

This *could* be a line noise or G3 file generation problem or something
along that lines, one would need to know if and how the data arrived.

And *this* is the well-known USR negotiation bug.  I'll show the log
file to my contacts at USR, and complain :-)

Thanks for all the data.

Fairly new firmware, but still broken.  *Sigh*.  Not enough complaints
from the user community.
