	Nothing in log.

	Strange.

$ show display

    Device:    WSA5:  [super]
    Node:      192.168.10.20
    Transport: TCPIP
    Server:    0
    Screen:    0

$ mc decw$examples:ico
Cannot open display
: non-translatable vms error code: 0xE4A, vms message:
%system-e-unsupported, unsupported operation or function

	On VAX side:

$ tcptrace 192.168.10.20 shows nothing

	Same constatation on Unix siide. Of course, I have checked that
	tcptrace runs as expected on known traffic:

$ tcptrace 192.168.10.20
   ICMP Type = 8 ECHO,   Code = 0 ,   Checksum = ^xE594 
   ICMP Identifier ^x24C3,   Sequence Number = 1 = ^x0001
