Have you tried using the "mode" command to reset the port?
After unloading the mouse driver...
mode com1:19200,None,8,1,P
COM#:b,p,d,s,P
Set serial port #=serial port number
b=baud rate - 110..19200
p=parity - Even, None or Odd
d=data bits - 7 or 8
s=stop bits - 1 or 2
P=Continuous retry on timeout
