Fixing/Disabling OSX's serial port handling

Hey guys,

I can't remember the details, but I remember reading something about how OS X handles serial/usb devices.

Some problems with the device resetting? Possibly when starting serial communication?

Is there any way to get OSX to act like windows in this respect?

I'm trying to get a PIC24 based microcontroller (with an FTDI chip) to work through VirtualBox, and I believe my problems are because of OSX.

Help?

Well the "issue" was that the widows FTDI driver had to be configured to assert RTS which activated auto reset. OSX/Linux did this by default.

This was specific to Arduino since it used rts or dtr for the auto reset. I'm not sure how it applies to a pic. Also, when using virtual box the guest OS is controlling the device, not the host OS.
