- there are level converters involved, you did not connect the msp430 
directly to the serial port? the later would damage the device.

- RX/TX connected to the right pin, not crossed over by accident?

no, it the msp430-bsl tool contains all that is needed ( a patch is 
indeed needed to be able to program flash on F149 chips with but erase 
works without it, there are however "extra erase cycles" needed, which 
msp430-bsl will take care of.)
