<div class="moz-cite-prefix">There is no "initial handshake" as such
for nodes at this level. You are not a node until you have
successfully logged in as a known entity to a node. Only at that
point does PC protocol happen - <b><u>if you are defined as a
node with that callsign</u></b> - on the node that you are
attempting to connect to. Otherwise you will be treated as a
user, given the contents of any MOTD file and sent a user prompt.<br>
<br>
So if one connects to a PC92 capable node; you have successfully
logged with user (+password if required); that username is a
callsign that is recognised as a node by the receiving node; you
are not locked out there (the default for some random node
callsign) - then this happens (GB7TLH-2 connecting to GB7DJK) as
shown from the receiving node's (GB7DJK) point of view:<br>

The stuff in black is normal logging on the receiving node
(GB7DJK) - and not passed across this connection. <br>
<br>
Connecting to an old style PC protocol node is much more verbose
but the PC18 -> PC20 -> PC22 pattern is the same. It just
has a big flurry of PC19/PC17 records in between these three
markers. The principle is the same.<br>
