Can screen add nl (new-line) for each (carriage-return)

gnu-screen

Edited:
I have data acquisition hardware that sends out serial data via UART into FTDI (serial to USB) device. The FTDI is plugged into USB port and its port name is /dev/ttyUSB0. This device outputs data in the following format:

data line 1\r
data line 2\r
...
data line n\r

I tried using screen to view the data by entering the following command:

screen /dev/ttyUSB0 115200

The screen begins to show all data on one line, so I see a single line flashing. How can I add a newline character at the end of each line so that the screen begins to separate the lines?

Original:
I am using a serial device that terminates lines with just carriage return. Is it possible to configure screen to add a nl (new-line) character for every cr character?

Thanks…

EDIT: Was not able to get this working with screen, picocom works great. I use the following command picocom -b 115200 --imap crcrlf /dev/ttyUSB0.

I know this isn't answering the exact question you have, but I normally jump to miniterm.py when presented with this kind of device because I've never found a way to do what you want with screen.

miniterm.py is minimal like screen and does the 'right thing' by default with \n. On the downside, my fingers don't know how jump around, quit and log, etc, so I still live in hope there's a way to do the right thing in screen

On OS X: 

miniterm.py /dev/tty.usbmodem1412

gives me nice output when screen would have scrawled all over the place.

pySerial comes with miniterm.py as far as I understand
