Hi,
I'm wondering what "error 121" is. I'm trying to connect to a Bluetooth Mate (Bluesmirf HID) through CoolTerm. I have an Arduino board programmed to just print "hello world" repeatedly, but for some reason coolterm refuses to connect to the bluetooth's comport, and Coolterm pings me with "Error 121" while trying to open a connection. I'm using Windows 8 (arrgh!) and an Arduino Uno.
Is there a list of errors and what they mean somewhere? I keep getting error messages, but it'd be nice to know what's specifically going wrong instead of just numbers...
