The cure Jim, is eliminate the prolific by replacing it with a FTDI 
dongle.  Prolific has a bug in its wakeup, throwing away the first byte 
rx'd. I threw mine into the out bin 2 decades ago. Was trying to use it 
to talk to a cm11a for a heyu interface.  Failed miserably.  Encourage 
owners to toss it and get the FTDI-usb<->serial which Just Works.
