I have some simple serial programs available that work on my TS-7390.
You can get the files here:
http://www.turbocontrol.com/simpleserial.htm
There are two programs and you can either run them both on your TS-7500
or run either program on a Windows or Linux i386 PC.
My examples do not compile EABI programs at this time. If the OS on
your TS-7500 runs OABI programs (like the TS-7390) then they should work.
If you want to try this get the file for ARM Linux and put the files on
your TS-7500 and try to run the compiler (ppcarm). If the compiler runs
then your OS is probably OK.
Let me know if I can help further.
