The OOPic IDE, when it plans to use a parallel cable to program the
EEPROM directly, looks for a real hardware parallel port at the
normal addresses (0x378, 0x278, 0x3BC). The IDE can not be convinced
that a USB serial cable (with a virtual COM driver) is a hardware
parallel port.
When the IDE does serial programming, it wants to talk to a COM port
in the range of 1..4 (version 5). This method works only for OOPic
versions equal to or later than B.2.0. In this case, the IDE talks
to the OOPic chip and the OOPic chip programs the EEPROM. A USB
cable often works but they may sometimes have a problem with the
OOPic-R version because the RS232 voltage levels are non-standard.
It will always work with a S version because you have to add an
external RS232 level shifter.
Neither of these approaches are going to work with your setup.
