Is there any interest in adding functionality if so?

When Arduino MCU (connected to esp mcu) generates too many logs to uart, updating sketches often fails. It would be great to have a second uart/tcp socket for logging, and the first uart use for firmware updates only.

Unused pin 3 (GPIO2) of ESP-01 would be good to use as the second uart rx in this case.
