I would prefer:
Environment="TERM=xterm"
ExecStart=-/sbin/agetty -8 --keep-baud %I @BAUDRATE@ $TERM

"xterm" as it is much more widely supported than "linux". Also, PuTTY 
uses "xterm" by default.
-8 to assume the tty is 8-bit clean and disable parity detection. I have 
had some issues where parity sometimes gets enabled even though the 
serial line is 8-bit clean and I end up with garbage on the serial terminal.
