Using the WIPsoft AT commands, WIP_NET_OPT_DEBUG_PORT is listed as one of the configuration options for +WIPCFG, allowing debug traces. It specifies ports 0-3 as valid ports with 0 being the default.
What are ports 0 through 3 associated with? One or more of the UART ports?
How are the debug traces activated? I did find the +ADLDBG command, but that appears to be valid only when employing the dev environment.
