I guess for core serial transfers it should be fairly simple to keep
things generic, ala:
int set_set(int baud, int parity, int bits, int stop) // 9600N81
int ser_xmt(char* buffer, int buflen)
int ser_rcv(char* buffer, int max, int timeout)
int ser_poll(void)
Maybe some:
int ser_enable(void)
int ser_disable(void)
...if you have interrupts
Interrupt driven serial I/O may offer extra complications, but
generically it's just:
void ser_int(void)
...I would think
And if it is a fully featured serial port, maybe some other pin level
functions.
You might find that a good place to look for more ideas is in a DOS
interrupt reference ("Ralf Brown's Interrupt List" springs to mind)
Beyond that you will need to decide what you will be doing with the
interface and what things a programmer would like to say to that
interface, such as:
int usb_handshake(...)
int usb_sendfile(...)
... etc. and take ir from there.
Good Luck,

One possible goal would be to re-implement Apples own serial protocol - see http://stud3.tuwien.ac.at/~e0026607/ipod_remote/ipod_ap.html
this is already quite a sophisticated interface (best ive seen on a mp3 player !) and would allow all current and future accessories to work with Rockbox...
Now if only someone would bring out a LCD remote (it IS possible with that protocl) that works with 5G and allows browsing... Im holding out for hte 'true video ipod' which is suipposed to have bluetooth. Im hoping to be able to control it from an old bluetooth phone acting as a wireless LCD remote...
