My thinking, after not having success with the CPAN definition, was to follow D2XX Programmer's Guide Version 1.3 definition and see if that worked (obviously it didn't and remained in the code, sorry about that).

The definition in CPAN: 

SetBitMode
  Parameters: {$mode}
  Return Success: TRUE
  Return Failure: FALSE
  Purpose: API Method - See FT_SetBitMode().
  Note: The following EXPORTS for BitModes are available for convenien
+ce:
    PFT_BITMODE_RESET
    PFT_BITMODE_ASYNCBB
    PFT_BITMODE_MPSSE
    PFT_BITMODE_SYNCBB
    PFT_BITMODE_MHBEM
    PFT_BITMODE_FOISM
    PFT_BITMODE_CBUSBB

Only asks for the $mode parameter, although I have tried this as: 

my $mode = FTDIdev->SetBitMode(0x03, 0x01); #also tried in dec with 3,
+ 1

print "My mode is: $mode\n";

This changes the printed $mode to 244 (0xF4) (as opposed to 245 (0xF5), which may indicate we have eliminated one error...). But again the program gets stuck at the write stage.

Thinking about it, how are the two outputs (two DB9 com ports) represented on the one chip? is this done with the mask? which would make require more than two bytes for masking the full 18 pins...

This would imply that 0x03 is trying to mask/write from the port belonging to ComPort6...
