Hello,
is there some command line utility/script enabled to check existance of
opened port on some remote machine? Or lists opened ports? I would like
something such as "REMOTENETSTAT machineIP port", or only "REMOTENETSTAT
machineIP".
I have tried to TELNET to remote machine to some port, but when the port
is opened and not supported for TELNET, the TELNET program freezes.

Telnet is really only useful for TCP ports and then only gives readable
results
if the service is "text based" (e.g., HTTP, FTP, SMTP, POP work fine.)

If you want telnet-like connections with more flexibility then try NetCat
(nc.exe).

Great ideas. OP may also like psexec.exe (Sysinternals) to run
commands on the remote system. netstat, fport etc.
