- I wonder if you're overflowing a buffer on the machine at the other
- end. I looks to me like the overall packet structure is OK, so there
- doesn't seem to be a gross compatibility problem. Checksum error
- probably indicates either some bytes are being garbled or dropped. If
- you're going through a terminal server, make sure both it and telnetd
- on your machine give a transparent path. It looks like you're getting
- the high order bit, so the other possibility is that its turned LF
- into CRLF or something like that. On our cisco terminal servers you
- have to do "term download" if you want a transparent path. We've also
- had to patch telnetd on the Unix machines for some releases, in order
- to give a transparent path.
