You can use attached lrz binary.  
Here is an example to transfer file via UART console:

1. transfer this lrz binary to /tmp of module by WINSCP
2. cd /tmp; chmod 777 ./lrz;
3. ./lrz -X cwe \</dev/ttyHSL1 \>/dev/ttyHSL1
4. In tera term, File → Transfer → XMODEM → tick 1K box → choose the file you want to transfer.
5. the file will be in /tmp with filename “cwe”.
