See page 31.34 of Vol 3 of the Interlisp Reference Manual for the description of
PUP.ECHOUSER.

! 	printed when a packet is sent
+	printed when an echo packet is sucessfully received
.	printed when an echo packet has not been received after INTERVAL ms.
?	printed when a packet is received, but is is neither an echo packet nor an
error packet
(late)	printed when an error [I think they mean echo...] packet is received,
after the echo request timed out.

So, "!+!.!+!.!+!.!+!.!+!." says you are getting an answer to  every 2nd packet.
Not very good.
