Terminal – How to Make Screen Go Down a Line and Start at Beginning on CR from Serial Device

I am connecting to a serial port using screen: screen /dev/cu.usbserial-A703XAOG. The device on the other end sends only a carriage return to separate lines. Screen only starts at the beginning of the line when receiving a carriage return, and does not go down a line, and thus overwrites the last line of output with the next line of output.

I can change the icrnl setting of the serial port, and it will convert the carriage return to a line feed. Although screen now goes down a line before writing the next line of output, it doesn't start at the beginning when receiving only a line feed.

I dumped the .termcap file using the Ctrl-A, Ctrl+.. I read up on termcap and I learned that:

If the terminal has a command that moves to the first column of the next line, that command can be given as nw (newline).

source

So this is my current ~/.screenrc file:

termcap SC nw=^M

Where SC matches the name in the dumped .termcap file.

This does not give the effect that I hoped for. Maybe the termcap command is not the way to go?

How can I make screen go down a line AND start at the beginning when receiving only CR from a serial device?

Edit:

Here is the output of sudo stty -f /dev/cu.usbserial-A703XAOG -a when screen is connected to the serial port:

        quit = ^\; reprint = ^R; start = ^Q; status = ^T; stop = ^S;
        susp = ^Z; time = 2; werase = ^W;

Edit:

I understand some software may solve this, for example, in PuTTY I would need to enable the "implicit LF in every CR" setting, and in Serial I would need to enable "Interpret Standalone CR as CRLF". But my question is specifically about screen, because that is the software I am using currently to connect to the serial port.

Edit:

Screen emulates the VT100 terminal, and it should recognize control sequences (source). I need to set "Automatic Linefeed Mode" (also known as new line mode). This should be done using the set mode control sequence with the parameter value 20: ESC [ 20 h.

How can I pass this control sequence to screen?
