One problem that I am aware that causes a lockup between the AMERISTAR board
and VMS systems is if the VMS systems are using trailer packets (if you
don't know what they are talk to your network administrator).  Currently
the AMERISTAR software does not know anything about trailer packets, so
what happens is that during an FTP transaction, the transmission starts
out with normal packets, but then the VMS side switches to trailer packets
for efficiency when transmitting large amounts of data.  This results in a
lockup.  Note that this does not occur with telnet or rlogin because
the packets here are small, and it only occurs occasionally with NFS
depending on the size of the data requested.  The fix is to turn off
the trailer option on the VMS side and everything will then work fine.
By the way, Suns as well as other machines recognize trailer packets,
but don't use them themselves, so you don't have a problem with them.

I have been using a Sun 4.0 for quite a while now and the only problem
that I am aware is with telnet.  The problem prevents you to login into
the Sun.
