i don't think so, based on this snippet of the source from the vnc
source rpm, the file VNCViewer.java:
vncServerName.setParam(host + ((port >= 5900 && port <= 5999)
? (":"+(port-5900))
: ("::"+port)));
so ":" is to be used for the display number, while "::" should be used
for the explicit port number but, somewhere, the code is forgiving
enough to let you use the actual port number with a single ":". i
don't think i'm interested enough to track down *that* bit of code.
