No, it's TCP. I stand corrected on Chris' plugin -- despite the "http"
string, it looks like his plugin is also using the text-based simple
"telnet" interface -- connect to TCP port 23 and each side exchanges
strings terminated by carriage returns. (I should look at that code
again -- are you using perl Async http libraries to get async TCP
responses? That would be awesome.) So I understand -- my Denon has
rs232 but not Ethernet, and I've only used telnet by way of a laptop
connected to the rs232 port and running "serial port server" software
to allow TCP connections to the rs232 port. It seems very odd that your
amp only listens for http (obvious from its responses) and not the
simple telnet protocol. Are you sure there's no firewall or packet
filter in the way? BTW, telnet's not a very good choice for interactive
debugging the Denons b/c the use of simple carroage returns without line
feeds means in apps like Hyperterminal and minicom you just see the same
line overwritten again and again.
