I had a problem like this, so I replaced the cheap converted with one "made" by a California company (it was much nicer, real drivers and instructions for $5 more). I got no output until I remembered that I might need a null modem adapter. Once I added that to mix everything worked like a charm (text started flowing).
Check you setup to see what kind of serial cable you have, as a regular "modem" cable will not work between a PC and an ALIX box. It needs to be the other kind (host to host).
