Pretty much impossible in Python. > But, trivial to implement as an extension :-) PEEK and POKE were intended to be used with memory mapped devices. Simplest example is the 6502 chip, which had no I/O bus -- it was all memory mapped. Want to change baud rate? poke a byte somewhere.
These days, the only device I can think of that's usually memory mapped is the video. And few programs talk to it that way. Now, INP and OUT (or various similar names) were for doing port I/o. But I suspect that modern systems aren't going to let you do much of that either. -- DaveA -- http://mail.python.org/mailman/listinfo/python-list
