No.  You can simply read /dev/ttyS0 and write to /dev/tty7:

In shell:

 $ (stty 9600 -paren -ixon -ixoff; cat) </dev/ttyS0 >/dev/tty7

Change the stty parameters as desired.

In Python, just open /dev/ttyS0, /dev/tty7.  Read from one and
write to the other.  

There are a couple different serial port modules that wrap up
serial ports into objects to hide the nasty termios stuff.

Google the group for terms like PosixSeral PySerial.
