* altos: Make stdio 8-bit clean by making pollchar return intKeith Packard2012-11-30
| | | | | | | | | | We were stealing one value (0xff) in the return value from pollchar to indicate 'not ready yet'. Instead of doing that, use the integer value -1 and have pollchar return an int instead of a char. That necessitated cleaning a few other bits to make sure that 0xff wouldn't get promoted to -1 on accident. Signed-off-by: Keith Packard <keithp@keithp.com>
