    I am attempting to use BFTP (running on a SPARC+ under 4.1 SunOs)
to move a file from a Unisys 5000/95 running SysV.3 and to a PC (I have
tried both ka9q's server and the one in tnvt from ftp software).  BFTP
needs to have one of the two remote machines ftp server support PASV
mode.  The Unisys box does not, the PC does.  Everything starts out
according to plan.  BFTP connects to both machines; it determines that
it can't put the Unisys machine in PASV mode and puts the PC in passive
mode instead.  The PC comes back and says to use port 20.  BFTP passes
the port information along to the Unisys machine.  It tries to make the
connect, and the PC refuses the connection.  The transcript of this
conversation is attached in the forwarded message.  Why does the PC
give a port number that it won't answer?  Does anyone have any ideas
as to what is going on?  Is there a way around this?  Thanks in advance.

Cheers--

Al
