Shouldn't it be blocked by default, and a call to fcntl() be required in order to set non-blocked mode? Example test program: #include main() { char Ch; Ch = getc(stdin); while (Ch != 'q') { putc(Ch, stdout); Ch = getc(stdin); } } If I run this program and type in 12345678, on Cygwin B20.1 and on my Unix worstation I see the following on my screen: 12345678 12345678 But if I try this with Cygwin v1.0 I get the following: 1122334455667788 Could this possibly be fixed by stty? If not, are fcntl() calls working with v1.0? P.S. This problem causes "bc" and "dc" to not accept backspaces (v1.0). Many thanks, Jim Grishaw.
