Hi again, from trying and decoding error messages I know the call to tcsetattr fails with an invalid input. The problem is caused by trying to set the field termios.c_ospeed, if left out the call is successfull. So I went the way trough the sources and have found something.
On FreeBSD 4.11 termios is defined like this: /usr/include/termios.h -> sys/termios.h struct termios { tcflag_t c_iflag; /* input flags */ tcflag_t c_oflag; /* output flags */ tcflag_t c_cflag; /* control flags */ tcflag_t c_lflag; /* local flags */ cc_t c_cc[NCCS]; /* control chars */ speed_t c_ispeed; /* input speed */ speed_t c_ospeed; /* output speed */ }; The fpc source file "" defines it as: <fpc-2.0.2>/share/src/fpc-2.0.2/rtl/freebsd/termios.inc type Termios = packed record c_iflag, c_oflag, c_cflag, c_lflag : longint; c_line : char; c_cc : array[0..NCCS-1] of byte; {$IFDEF BSD} c_ispeed, c_ospeed : longint; {$endif} end; TTermios=Termios; Note the line in pascal saying "c_line: char" which is missing in the systems declaration. This is an error, insn't it? Marc _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
