[slime-devel] incompatible protocol?

[Joe Corneli]

Hi -- I am getting weird results with my remote slime connection.

I am running and SBCL 0.9.16 and swank from SLIME 2.0 on a remote
linux box, and connecting with SLIME 2.0 on 

  GNU Emacs 22.0.91.3 from 2006-12-16.

When I `slime-connect' I get this prompt:

Protocol version mismatch. Continue anyway? (yes or no) 

If I type yes, then I can do things:

CL-USER> (asdf:operate 'asdf:load-op :elephant)
; loading system definition from
; /usr/local/lib/sbcl/site-systems/elephant.asd into #<PACKAGE "ASDF0">
[...]

But I can't seem to get values back! --

CL-USER> (+ 1 1)
CL-USER>

On the other hand, I can print:

CL-USER> (format t "~a" (+ 1 1))
2

Is there a way to get the normal expected behavior back?
