It's been a while. Due to reasons I have now downgraded Emacs to 21.3,
and I am using Tramp 2.0.36. /bin/sh is now ash (NetBSD's Bourne shell).

I still have a similar problem, however. But now the Tramp debug log
looks like this:

# Opening connection for `root' using `sudo'...
# Waiting for prompts from remote shell
# Waiting 60s for prompt from remote shell
# Found remote shell prompt.
$ unset correct
unset correct\n[[Regexp `\(^[^#$%>
]*[#$%>] *\|^[^#$%>
]*[#$%>] *\(\[[0-9;]*[a-zA-Z] *\)*\)\'' not found in 60 secs]]

I have also tried running the following commands in sequence:

(start-process "sh" "sh" "/bin/sh")
(process-send-string "sh" "echo N\n")
(process-send-string "sh" "echo R\r")
(process-send-string "sh" "echo RN\r\n")

Which results in this:

$ echo N
N
$ echo R
R
$ echo RN
RN
$ 
$ 

Is this giving you any clues?
