Uart interface to propeller microcontroller

Is there any way to interface the psp to the parallax propeller microcontroller? I want to interface a gsm modem to the psp and store it in the umd bay, using a simple homebrew program to send AT commands (like ATD15555551234) to the modem from the psp. maybe like simple numbered button clicks to send commands? the propeller supports bit-banging uart using 2 of its cogs with 6 of them left over for, i dont know, harddrive interface, gsm modem, gps, all kinds of possibilities. wich serial port should i use for ttl level serial? any coding suggestions for accessing this serial port? i have eclipse installed and a basic understanding of coding for the psp and can live debug with usbhost.





Edit:I think I have found the software to do the trick

Download Mypsp Robotics Here

Also, the gsm modem i am looking at also has built-in gps sirf 3. can I mod the map this source to send a query data command through the uart or remote or usb wichever port is easiest, preferrably one inside the psp so I still have access to the external ports

SD slot and OLED display
I think it will all fit in the umd drive with the drive removed. I may have to add a higher capacity battery for improved battery life and a custom umd door for it to fit. possibly I could also buy the chotto shot cam and internalize it as well for a wifi gaming cameraphone with gps. sweet.

This is something along the lines of what I would like the psp phone interface to look like. I am trying to make this work with the lte engine but, alas, my efforts have failed. I have edited the lte user interface example by adding a button and event reciever to go with it. I eventually want to move things around and add the buttons, wording to go along with it (when you type a number and press dial a window should pop up and say "ATD5555555555" or whatever number you enter in the text input field)/serout that data thru remote port. After I did my first little bit of editing, cleaned, recompiled, reset psp link, and debug UserInterface.prx, click debug button twice to find that the portion of the code that I have edited does not show up on the psp, just the demo as it was before i edited the c file. What the heck am I doing wrong?

I also tried to use the code tags to post this but I lost all of my code structure. Any help is much appreiciated.
