Yes, I was speaking about PS1 setting.

Tramp sets the $TERM environment variable. So you could something like

  [ $TERM = "dumb" ] && PS1='$ '

Tramp needs a special prompt, in order to distinguish command output
and, hmm, the prompt. Overriding this setting confuses Tramp.

Hmm, it returns strange uid and gid (4294967295). You 'll see it when
calling on the remote host

  \stat -c ' %u %g' /cygdrive/d/PFlowAcc/server

What do you see when calling this:

  ls -dn /cygdrive/d/PFlowAcc/server

That's because of not knowing uid/gid correctly.

\bash would suppress any alias "bash" you might have declared, calling
the program "bash" instead.
