Propforth 3.4 HiRes VGA reset issue about propforth

I started a FullDuplexSerial object to send back debugging strings to the PC 
via the onboard FTDI chip.
Everything works well.

But when I disconnect the USB cable, some debugging strings that are still 
being sent to the FTDI chip will cause the FTDI chip to reset the propeller.
Is there a way around this?

Just disable the Serial Driver. More exactly make pin 30 an input or low.

by adding a buffer in their next board rev, you can work around the issue by 
adding 4.7K pull-ups to A30 and A31.

Issue wih FDTI usb to serial chip

Plug usb cable into cheap hub when not connected to PC when having issue with 
demoboard etc

other choice is to add jumper to fdti chip reset line on DTR per propeller
