Something you could try is a terminal program on the PC and COCO and see if
the serial cable is actually working correctly.

The other thing is are you using a CoCo3 version of the HDBDOS DW ROM?
There are 3 versions of the ROM.  One for the CoCo1, one for the CoCo2, and
finally one for the CoCo3.  Each have dif baud rates for the bitbanger port.
