How can I make screen go down a line AND start at the beginning when receiving only CR from a 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](https://www.freebsd.org/cgi/man.cgi?query=termcap&sektion=5&manpath=4.3BSD+Reno) 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: speed 9600 baud; 0 rows; 0 columns; lflags: -icanon -isig iexten -echo echoe echok echoke -echonl echoctl -echoprt -altwerase -noflsh -tostop -flusho -pendin -nokerninfo -extproc iflags: -istrip -icrnl -inlcr -igncr -ixon -ixoff -ixany -imaxbel -iutf8 -ignbrk brkint -inpck ignpar -parmrk oflags: -opost -onlcr -oxtabs -onocr -onlret cflags: cread cs8 -parenb -parodd -hupcl clocal -cstopb -crtscts -dsrflow -dtrflow -mdmbuf cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = ^@; eol2 = ^@; erase = ^?; intr = ^C; kill = ^H; lnext = ^V; min = 100; 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](https://putty.org) I would need to enable the "implicit LF in every CR" setting, and in [Serial](https://www.decisivetactics.com/products/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](https://www.gnu.org/software/screen/manual/html_node/Control-Sequences.html)) . I need to set "Automatic Linefeed Mode" (also known as [new line mode](https://vt100.net/docs/vt100-ug/chapter3.html#LNM)) . 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?
