the telnet example was to show that there were a connection problem. for me the server is (still) not responding, but anyway, if you want to test some connection over ssl you need no telnet but openssl and type something like :
openssl s_client -connect login1.swipnet.se:443
POST /login.php
username=xxxxxxxxxx;password=yyyyyy;
note the CR/LF at the end.
I recommend you read more about HTTP if you need to debug such transaction, the next step in debugging is to use a proxy that will do the encryption and you can sniff what happend between your client machine and the proxy , quite tricky anyway.
