I uploaded the example 'hello world' sketch to my Arduino but Windows is never able to establish a connection.http://playground.arduino.cc/Code/SerialIP
On the WinXP (guest) side, when it tries to connect, I see the rx led on the board blink.. and the data the arduino gets is "CLIENT".
I'm not familiar with the SLIP protocol, but since the Mega2560 is receives seemingly non-random characters, I'm assuming the baud rate / com port connection is ok.. yet it never transmits anything. As a quick test I changed the setup to do an infinite loop of Serial.write ('h'), and verified that the arduino is transmitting properly (I see the tx blink & the h's on hyperterminal).
But why doesn't the arduino respond to the "CLIENT" connection attempt? Has anyone tried this library or can point me in the right direction?
I was thinking of changing all references in example source code from Serial to Serial 1 (or 2, or 3) to see if using another port might make a difference, but need to purchase a ttl/232 converter.
UPDATE: On a different (VM XP) machine instead of windows sending CLIENT (and expecting CLIENTSERVER), I see the Arduino receives "LET" 3 times. Anyone know of a VM Linux distro that might have SLIP support built-in that I could try?
