More details, certainly;
I've just been given a Freescale mc1322x chip to interface to and run. The chip lives on a tiny dongle board, and communicates with a FTDI FT232R chip, which then is connected to the USB connection. So its a USB Serial bridge, they cannot be disconnected.
This dongle will be plugged in and out all the time.

I wonder, ...wait a second...Amazing. OK, so there's actually a perl module built for the FTDI interface directly. This means I don;t actually have to use Win32::CommPort or Win32::Serial, I can use Win32::FTDI::FTD2XX.
I never thought to look until you asked for a bigger picture. Very silly. This is what happens when you have a three week old baby keeping you up all night.
I spent about a year working on the previous version of the Freescale chip, mc1312x, the USB R232 bridge for that was completely unsupported by anyone, and I actually had to write my own Linux driver for it to work. I was handed the new version, I noticed the FTDI chip, and forgot about it since my previous code worked.
But I never did this plugging / unplugging business.
OK, so I will have to see if this new module makes my problems go away. Roll on Monday morning. Yay.
I'll report back with my results. Assuming this baby doesn't drive me mad in the mean time.
