The OpenEdge Hive

Is it possible to create an secure socket connection for posting data using:

CREATE SOCKET Socket$h.
Socket$h:CONNECT('-H ' + postData.Host + ' -S ' + postData.Port) NO-ERROR.

(Some background info: I need to make an connection with the UPS-server. This works but it responds with a http 400-error:

Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please.
)

Anyone encountered this problem before? How did you solve it? Or do you have an idea in which direction to look for the solution.

Thanks in advance.
