The "serial port" setting, not the "tcp port" setting.
The telnet protocol is not just raw data. The 0xFF byte is an escape code for commands (and a 0xFF needs to be repeated twice pass an actual 0xFF). There are a few commands including those to send a rs232 break signal or to negotiate options such as serial port baud rate (serial ports don't negotiate a speed, so you have to be able to configure the right speed on both ends of the communication)

Oh that makes more sense, thanks! > Serial ports don't negotiate a speed, so you have to be able to configure the right speed on both ends of the communication This is actually why I was asking -- I'm messing around with an espflash-like clone and wanted this feature; so is the idea that its easier to set up the negotiation because of the command structure of telnet (e.g. pattern match on rx `telnet send ayt`)?
