No correct signal from ATMEGA162 UART
Although you stated that you use \$1\$ stop bit, \$\texttt{USBS0}\$ enables two. But that should not interfere with anything.

Bigger problem is in baud rate generator. Baud rate in normal mode is calculated as \$\dfrac{f_{osc}}{16\cdot (\texttt{UBRR+1})}\$. So UBRR is \$\dfrac{f_{osc}}{16\cdot BR}-1\$ and for \$4.915200\, \mathrm{MHz}\$ it is \$31\$, not \$51\$.

Edit: Another problem found, incorrect bit shifting in UART configuration register C. It should be \$\texttt{3&lt;&lt;UCSZ00}\$, not \$\texttt{3&lt;&lt;UCSZ01}\$.
