/* This code tries to use several ANSI C features, including
prototypes, stdarg.h, the const qualifier and the types void
(including void * pointers) and unsigned char. By default it will
use these features if the compiler defines __STDC__. If your
compiler supports these features but does not define __STDC__, you
should set ANSI_C to 1. If your compiler does not support these
features but defines __STDC__ (no compiler should do this, in my
opinion), you should set ANSI_C to 0. In most cases (or if you're
not sure) just leave the line below commented out. */
/* Set USE_STDIO to 1 if data files should be read using the stdio
routines (fopen, fread, etc.) rather than the UNIX unbuffered I/O
calls (open, read, etc.). Unless you know your stdio is really
rotten, you should leave this as 1. */
/* Exactly one of the following macros must be set to 1. Many modern
systems support more than one of these choices through some form of
compilation environment, in which case the setting will depend on
the compilation environment you use. If you have a reasonable
choice between options, I suspect that TERMIO or TERMIOS will be
more efficient than TTY, but I have not done any head to head
If you don't set any of these macros, the code below will guess.
It will doubtless be wrong on some systems.

not make a choice above. It is in this file to make it easy to

/* On some systems a write to a serial port will block even if the
file descriptor has been set to not block. File transfer can be
more efficient if the package knows that a write to the serial port
will not block; however, if the write does block unexpectedly then
data loss is possible at high speeds.
If writes to a serial port always block even when requested not to,
you should set HAVE_UNBLOCKED_WRITES to 0; otherwise you should set
it to 1. In general on System V releases without STREAMS-based
ttys (e.g., before SVR4) HAVE_UNBLOCKED_WRITES should be 0 and on
BSD or SVR4 it should be 1.
If HAVE_UNBLOCKED_WRITES is set to 1 when it should be 0 you may
see an unexpectedly large number of transmission errors, or, if you
have hardware handshaking, transfer times may be lower than
expected (but then, they always are). If HAVE_UNBLOCKED_WRITES is
set to 0 when it should be 1, file transfer will use more CPU time
than necessary. If you are unsure, setting HAVE_UNBLOCKED_WRITES
to 0 should always be safe. */

/* When the code does do a blocking write, it wants to write the
largest amount of data which the kernel will accept as a single
unit. On BSD this is typically the value of OBUFSIZ in
<sys/tty.h>, usually 100. On System V before SVR4 this is
typically the size of a clist, CLSIZE in <sys/tty.h>, which is
usually 64. On SVR4, which uses STREAMS-based ttys, 2048 is
reasonable. Define SINGLE_WRITE to the correct value for your
system. If SINGLE_WRITE is too large, data loss may occur. If
SINGLE_WRITE is too small, file transfer will use more CPU time
than necessary. If you have no idea, 64 should work on most modern
/* Some tty drivers, such as those from SCO and AT&T's Unix PC, have a
bug in the implementation of ioctl() that causes CLOCAL to be
ineffective until the port is opened a second time. If
HAVE_CLOCAL_BUG is set to 1, code will be added to do this second
open on the port. Set this if you are getting messages that say
"Line disconnected" while in the dial chat script after only
writing the first few characters to the port. This bug causes the
resetting of CLOCAL to have no effect, so the "\m" (require
carrier) escape sequence won't function properly in dialer chat
#define HAVE_CLOCAL_BUG 0
/* On some systems, such as SCO Xenix, resetting DTR on a port
apparently prevents getty from working on the port, and thus
prevents anybody from dialing in. If HAVE_RESET_BUG is set to 1,
DTR will not be reset when a serial port is closed. */
/* The Sony NEWS reportedly handles no parity by clearing both the odd
and even parity bits in the sgtty structure, unlike most BSD based
systems in which no parity is indicated by setting both the odd and
even parity bits. Setting HAVE_PARITY_BUG to 1 will handle this

/* On Ultrix 4.0, at least, setting CBREAK causes input characters to
be stripped, regardless of the setting of LPASS8 and LLITOUT. This
can be worked around by using the termio call to reset ISTRIP.
This probably does not apply to any other operating system.
Setting HAVE_STRIP_BUG to 1 will use this workaround. */
/* TIMES_TICK is the fraction of a second which times(2) returns (for
example, if times returns 100ths of a second TIMES_TICK should be
set to 100). On a true POSIX system (one which has the sysconf
function and also has _SC_CLK_TCK defined in <unistd.h>) TIMES_TICK
may simply be left as 0. On some systems the environment variable
HZ is what you want for TIMES_TICK, but on some other systems HZ
has the wrong value; check the man page. If you leave this set to
0, the code will try to guess; it will doubtless be wrong on some
non-POSIX systems. If TIMES_TICK is wrong the code may report
incorrect file transfer times in the statistics file, but on many
systems times(2) will actually not be used and this value will not

other. If your system has the setreuid function, don't worry about
this define, or about the following discussion.
If you set HAVE_SAVED_SETUID to 0, you will not be able to use uucp
to transfer files that the uucp user can not read. Basically, you
will only be able to use uucp on world-readable files. If you set
HAVE_SAVED_SETUID to 1, but your system does not have saved set
user ID, uucp will fail with an error message whenever anybody
other than the uucp user uses it. */

the setreuid function is broken. It should be possible to use
setreuid to swap the real and effective user ID's, but on some
systems it will not change the real user ID (I believe this is due
to a misreading of the POSIX standard). On such a system you must
set HAVE_BROKEN_SETREUID to 1; if you do not, you will get error
messages from setreuid. Systems on which setreuid exists but is
broken pretty much always have saved setuid. */

/* If you use other programs that also lock devices, such as cu or

is locked. This is typically done by creating a lock file in a
specific directory; the lock files are generally named
LCK..something or LK.something. If the LOCKDIR macro is defined,
these lock files will be placed in the named directory; otherwise
they will be placed in the default spool directory. On some HDB

The HDB style is to write the locking process ID in ASCII, passed

The V2 style is to write the locking process ID as four binary
bytes in the host byte order. Many BSD derived systems use this
type of lock file, including the NeXT.
SCO lock files are similar to HDB lock files, but always lock the
lowercase version of the tty (i.e., LCK..tty2a is created if you
are locking tty2A). They are appropriate if you are using Taylor
UUCP on an SCO Unix, SCO Xenix, or SCO Open Desktop system.
SVR4 lock files are also similar to HDB lock files, but they use a
different naming convention. The filenames are LK.xxx.yyy.zzz,
where xxx is the major device number of the device holding the
special device file, yyy is the major device number of the port
device itself, and zzz is the minor device number of the port
