rcp doesn't work one way

[Marty]

Between two machines (a sun386i and a sun3/280) I can:
	1) rlogin both ways with no problem
	2) rsh both ways with no problem
	3) rcp only one way (sun386i initiates the transfer).

The sun3 is running SunOS 3.5.

The sun386i is running SunOS 4.0.1.

The sun386i can send/receive stuff via rcp from the sun3.

On the sun 3:
	1) when I send it fails silently 
	2) when I try to bringover a file I get:
	rcp: protocol screwup: mtime.sec not delimited
	
I'm stumped -- what should I look for?
