Re: tramp (2.2.3-24.1); Using tramp to run ess-remote session. Submitting more than one line of code at a time, causes emacs to wait indefinitely.

[Tobias Muhlhofer]

Hi, Michael:

Sorry about that. Here is the debug tramp buffer. Same steps as before

By the way, between steps 3 and 4, tramp's auto-complete actually
worked to lead me to the starting directory that I wanted for R on the
remote machine.

Anyway, here is the output:

---------------------------------------------------

I have redacted the actual path to help a little with security.

One guess (by someone who doesn't quite understand everything that's
going on here): would the expression 'exec env
PS1=/scpc\:address@hidden:\ \#\$\', imply that the only
two available prompt characters are "#" and "$"? That would present a
problem, since the prompt character in R's interpreter is ">". But
maybe that means something else.

Thanks!
