Please do.  The list of people who have had trouble with a pl2303 based cable 
forms over there, waaaaay over there.  FDTI based cables, plugged into the 
exact same position in the system seem to Just Work(TM).  We either have a 
funkity pl2303 driver, or the chipset doesn't quite meet usb specs.  The first 
byte of a packet after a quiet period may be garbled.  heyu, the x10 program, 
cannot do anything that even approaches x10 reliability (and that's an oxymoron 
right there) with one of them between the cm11a and a usb port.

They also cannot be used between a UPS and a UPSD monitoring program, the 
frequent "loss of communications", in the case of one such monitor program, 
will cause the daemon to issue shutdown commands several times a day.
Life is too short as it is, to put up with that.
