other way of testing for 4.1BSD, or add yet another compile-time switch.

include it here, and then the second include is harmless because in Red Hat
Linux (the only place where you find baudboy.h) fcntl.h is protected from
multiple inclusion by _FCNTL_H. - fdc, 10 May 2004.
NOTE: Although Linux /usr/sbin/lockdev obviates the need for setuid or
setgid bits to access the lockfile, C-Kermit will still need them to access
the serial port itself unless the port is open for world read/write.
Normally setgid uucp does the trick.

Variables available to outside world:
dftty -- Pointer to default tty name string, like "/dev/tty".
dfloc -- 0 if dftty is console, 1 if external line.
dfprty -- Default parity
dfflow -- Default flow control
ckxech -- Flag for who echoes console typein:
1 - The program (system echo is turned off)
0 - The system (or front end, or terminal).
functions that want to do their own echoing should check this flag
before doing so.
flfnam -- Name of lock file, including its path, e.g.,
"/usr/spool/uucp/LCK..cul0" or "/etc/locks/tty77"
lkflfn -- Name of link to lock file, including its paths
haslock -- Flag set if this kermit established a uucp lock.
lockpid -- PID of other process that has desired line open, as string.
backgrd -- Flag indicating program executing in background ( & on
end of shell command). Used to ignore INT and QUIT signals.
rtu_bug -- Set by stptrap(). RTU treats ^Z as EOF (but only when we handle
SIGTSTP)
Functions for assigned communication line (either external or console tty):
sysinit() -- System dependent program initialization

ttgspd() -- Get (read) the the transmission speed of the tty.
ttpkt(speed,flow,parity) -- Put the tty in packet mode and set the speed.
ttvt(speed,flow) -- Put the tty in virtual terminal mode.
or in DIALING or CONNECTED modem control state.

ttscarr(carrier) -- Set carrier control mode, on/off/auto.
ttinl(dest,max,timo) -- Timed read line from the tty.
ttinc(timo) -- Timed read character from tty.
myread() -- Raw mode bulk buffer read, gives subsequent
chars one at a time and simulates FIONREAD.
myunrd(c) -- Places c back in buffer to be read (one only)
ttchk() -- See how many characters in tty input buffer.
ttxin(n,buf) -- Read n characters from tty (untimed).
ttol(string,length) -- Write a string to the tty.
ttoc(c) -- Write a character to the tty.
ttflui() -- Flush tty input buffer.
ttsndb() -- Send BREAK signal.
ttsndlb() -- Send Long BREAK signal.

ttunlck() -- Unlock tty device.
For ATT7300/Unix PC, System V:
attdial(ttname,speed,telnbr) -- dials ATT7300/Unix PC internal modem
offgetty(ttname) -- Turns off getty(1m) for comms line
ongetty(ttname) -- Restores getty() to comms line
*/
/*
Functions for console terminal:
congm() -- Get console terminal modes.
concb(esc) -- Put the console in single-character wakeup mode with no echo.

conoc(c) -- Unbuffered output, one character to console.
conol(s) -- Unbuffered output, null-terminated string to the console.
conola(s) -- Unbuffered output, array of strings to the console.
conxo(n,s) -- Unbuffered output, n characters to the console.
conchk() -- Check if characters available at console (bsd 4.2).
Check if escape char (^\) typed at console (System III/V).
coninc(timo) -- Timed get a character from the console.
congks(timo) -- Timed get keyboard scan code.
conint() -- Enable terminal interrupts on the console if not background.
connoi() -- Disable terminal interrupts on the console if not background.
Time functions
msleep(m) -- Millisecond sleep
ztime(&s) -- Return pointer to date/time string
rtimer() -- Reset timer
gtimer() -- Get elapsed time since last call to rtimer()
