since TCP/IP is totally packet agnostic, thou shalt not rely on it's
packetizing capabilities.
if your receiver emits packets the same as you sent them, then you were
merely lucky.

with TCP/IP you need a application-layer packetizing mechanism,
in FUDI this is the famous ";".
iirc, in more popular protocols (like HTTP, SMTP, FTP) it is usually CRLF.
