Can a PICmicro programmer which normally uses a Serial port be used on
a USB port with a Serial to USB adaptor?
In most cases yes how ever, Some USB to Serial converters are not 100%
compatible and thus may effect the way the programmer works.
Voltage levels is the number one rule... Some of these converters do
not generate the expected out of voltage and current on the control
lines that the programmer wants to see.
Also, there are a few that do not support the control lines to 100%..
