it would beyond awesome if esp-link could understand rfc2217 commands (to set properties of the serial port).
My use-case: I have a Raspi3 with Octoprint, where in Octoprint I would like to send gcode over the network to an esp8266 (D1 mini) running esp-link, which in turn pipes it to the serial port on my 3d-printerboard
This then fails in Octoprint with the following error message:

Hi,
it would beyond awesome if esp-link could understand rfc2217 commands (to set properties of the serial port).
My use-case: I have a Raspi3 with Octoprint, where in Octoprint I would like to send gcode over the network to an esp8266 (D1 mini) running esp-link, which in turn pipes it to the serial port on my 3d-printerboard
I have set up Octoprint to enable redirection of the gcode output to a network serial port.
This then fails in Octoprint with the following error message:
