OK, I get this when I do slime-connect in XEmacs 21.5 beta18:

in LW 4.4:
WRITE: (:open-dedicated-output-stream 1381)

in XEmacs:
nil
  byte-code("..." [error message "net-read error: %S" ding sleep-for 2 debug
nil (slime-net-close proc) ((error)) "PANIC!"] 3)
  slime-process-available-input()
  slime-net-filter(#<network connection "SLIME Lisp" (4005 . "127.0.0.1")
state:run> "

I tried with gnu Emacs 21.3.1 and got:

in LW:
WRITE: (:open-dedicated-output-stream 1401)

in gnu Emacs:
Debugger entered: nil
  byte-code("ÁÂ\",HC(B ,HDÅ(B!,HF(B ,HGÈÉ,_ÀÊ(B!,G"(B [error
message "net-read error: %S" ding sleep-for 2 debug G89685 (slime-net-close
proc) ((error)) "PANIC!"] 3)
  slime-process-available-input()
  slime-net-filter(#<process SLIME Lisp> "

On the Lisp side I call this:
(swank::create-swank-server 4005 :spawn #'swank::simple-announce-function t)
