Maybe minicom? I am not sure

Minicom, C-Kermit and Seyon are the three most common serial interface applications for Linux. All are open-source. Does your program need to communicate with an existing remote host? If so, you need to know about the nature of that remote host's file transfer capabilities. Using straight serial protocols, the four most common file transfer protocols are Kermit, Xmodem, Ymodem, and Zmodem. There may be others.

the java communications API (also known as javax.comm) may be something to look at

i never tried this, but would 'cat $file > /dev/ttys0' then 'cat /dev/ttys0 > $file' on the receiver work ?

It should, as long as you have sufficient privilege on the device, and as long as the transmission parameters (bit rate, parity, stop bits, handshake, etc) and 'processing' of the stream have be properly configured a priori. The receiving situation may have problems determining EOF, since the device is a character device, and just sees the channel as a conduit through which to ship bytes.
