This! I still recall using zmodem not that long ago for this exact purpose of sending firmware blobs over just a serial connection.

- waste_monk 3y agoWe have switches purchased in the last few years that use zmodem for firmware upload and recovery. Annoyingly it still supports a maximum of 115200 baud, even though the serial port on the switch is physically USB-C, so on the one occasion we had a switch brick itself and had to use zmodem "in anger" it took quite a long time to upload the replacement firmware.
