I'm having difficulty getting a VAX 750 to communicate with a pair
of SUN-3's over Ethernet.  All are running 4.2bsd.  The VAX has an
Interlan NI1010A-S1 board and an Interlan tranceiver;  the SUNs use
3Com tranceivers.

The problem comes when using rcp to send files from the VAX to either
SUN - the copy fails (after a long wait) if the size of the file
being copied exceeds 1023 bytes.  The other 4 paths (either SUN to the
VAX, either SUN to either SUN) between the systems work fine.  Rlogin
works fine in all directions.

I've swapped tranceivers, Interlan <--> 3Com, and Interlan has twice
sent me replacement boards, all with no success.

I would be grateful for any suggestions, or hints as to what to try next.

    Thanks,
    Carl Shapiro
