looking for a quick sanity check

[cncmachineguy]

After 10+ years of playing with PIC's, Its time to talk to a puter. I have attached my test schematic for critique. Please note all the optional pin names may not be correct on the PIC, I tend to get rather lazy about changing all the names. But I have connected the correct pins for ICSP and Tx2/Rx2.

Heres my setup I am thinking about:
Laptop running win7-64
USB->RS232 cable
ICD3->ICSP
Power circuit from ICD3 through ICSP for serial testing
Some sort of hyperterminal style PC side (prolly Daves (Mackrackit) serial.py code)
Hardware USART PIC side
PBP 2.6a
Int clock

Now I would love to use USB instead of RS232, but that seems like trying to run when I can't even walk yet. So I guess my question is will the above collection of parts along with the proposed circuit give me the ability to make this work?

I am used to using the PicKit2 so the programming header looks off, what are you using?

I would not tie the extra pins on the DB9 together, just use 2,3, and 5 as you have them.

thanks Dave. I use ICD2 or 3 So all my ICSP headers are custom. I do think I will configure it to be the same as Pickit2 as it seems to be populer.
I will remove the jumpers, that came from the 3311 datasheet.

Any thoughts on the usb->232 cable? will this work?

I must have a different data sheet, I do not see the jumpers. But I am still half asleep...

Are you talking one of those USB to serial conversion cables? If so, yes. Those conversion cables will also work if you are using SERIN2/SEROUT2 inverted without a MAX chip.

One thing to be aware of is that USB-serial adapters require conversions on both ends, serial-to-USB & USB-to-serial. This can be a factor in time critical applications. IOW, 9600bps will not be a true measure of throughput. I have encountered problems with some bootloaders when using USB-serial and, also, with ethernet-serial adapters. Also, while not a factor here, some USB adapters do not handle all of the modem control lines like DTR, etc.

I'm not sure what you mean here

No, I am the one asleep, after looking at the datasheet again, I realized that came from some circuit I found on the net.

Is this Yes it will work as I want, and also it will work using SERIN2/SEROUT2...?
The target puter for this app has an actual rs232 port, but I am wanting to play with my laptop first.
