You can probably just open HyperTerminal on your PC, and get the baud 
rate right, standard coco expects 600,N,8,1

Then do something on the coco that causes bytes to be written to serial, 
either a LLIST of a "hello world" program, or else print to the printer 
with PRINT #-2,"HELLO"

If coco tries to PRINT or LLIST, and appears to hang forever, it is 
waiting for CD/handshake (etc), and your cable may not be signalling 
that.  I've used these pokes in the past to disable/disregard CD...

10 POKE &HA2C7,36
20 POKE &HA2F7,36

... then try your PRINT...

30 PRINT #-2,"HI THERE"
