Just to remind myself, because I keep having to look this up: you can reset a Pico by setting the USB serial port baud rate to 1200, like so:
`stty -F /dev/ttyACM0 1200`
#pico

@th it's an explicit feature; I think it's a pretty neat idea, using the (effectively pointless) baud rate for OOB signaling.

@phooky @th [Marks down that @phooky called 1200 baud "effectively pointless" on his naughty list]

@elb @th sorry! I meant that baud rate is effectively pointless for USB serial devices. For traditional serial connections, 1200 baud is still important for those who haven't yet achieved the inner peace necessary to accept the 110 baud connections of our enlightened ancestors

@phooky @elb or the tranquility of forty-five baud for communicating with the ancient ones.

@th @elb now you have me wondering if there was ever an acoustic coupler for the model 15...

@th @phooky @elb and now you've given me the very silly idea of transmitting Hellschreiber via piezo beeper to matrix displays, aargh

@th @elb @scruss If you haven't already seen it, the Secret Life of Machines episode about fax machines has a terrific bit (about 5:20 in) about Pantelegraphes, which date to the 1860's.

@phooky @th @elb the SLoM episode is good

The drum + photocell on a lead screw was used in lots of things like photo wires, duplicator 'spark' copiers and drum scanners (into the early 2000s)

Hellschreiber is an analogue dot-matrix printer. It can't send images more than 7px high, so it's mostly text Sync errors make the text go all wavy. The K3NG keyer for Arduino still (I think) has Hellschreiber sending
