Hi;
I am trying to use an X.25 connection for an international file
transfer link between New Zealand and Spain.

I can establish the link just fine, which is between two Unix
boxes.  It doesn't work as a normal terminal, i.e. the remote
PAD does not send a line until it is terminals, which I assume is
due to the setting of the data forwarding signal (X.3 PAD parameter
SET 3:2).  I tried setting SET 3:126 which should make all ASCII
control characters and DEL become forwarding characters, but 
this does not fix the problem - it seems that I am only setting
the parameters in my local PAD.  How can I set the parameters
in the PAD in Spain remotely?

I should say that I am using a dial-up X.25 PAD via a V22bis modem
(asynch).  Maybe I should make the connection first, then set my local 
PAD parameters - does this automatically get passed on to the remote
PAD ??

Now file transfer - I have got Kermit working, since it uses CR to
terminate its packets.  It's SLOOOOOOW, especially because it has
no windowing and slow turn-around.  I want to get ZMODEM working,
but of course I have never done this before.  Can some kind soul
tell me the optimum tricks/settings for Zmodem and the PAD X.3 profile
for this to succeed?

Thanks.
(mail and I will summarize).
