+++ATH0 brings memories. In my early days of IRC, it used to wreck havoc to write that in crowded channels. It blows my mind that modems processed that string no matter the context.
- eythian 8y agoModems have no concept of context, and out of band signalling was optional. It was _supposed_ to be +++[wait 0.5s]AT... but that pause was patented by Hayes, so to avoid patent issues, many cloners didn't require it. At least, that's the story I heard.
- xenadu02 8y agoIt seems strange they didn't use DTR since RTS/CTS are usually used for hardware flow control. I can see the point of DSR, which tells the computer the modem exists... but there is no point in the modem looking for the computer. In theory the PC could have asserted DTR whenever it wanted to activate the control channel.
