Often just a resistor in the MM2 RX line. I have used it in the past when connected to a laptop for the console. Perhaps INV is only available on COM1: If your modules work on a Pico then they must be TTL serial and don't require inversion. Edit INV should also be available on COM2: but not on any "Embedded C Module" ports. Edited 2023-09-20 18:06 by phil99
