* Corrected a bug in modem read. Appended the '\0' char in
  read buffer.

Tue May  2 20:42:03 MET DST 1995
* better handling of alarm timeout on device open.
* contitional compilation for MDM_CHECK_DEVICES
* int clear_line(int fd, int waittime) new function (stolen from mgetty)
  to clear an opened line.

Sat Apr 29 19:07:05 MET DST 1995
* savetty: de-erased, period.
* Now call.c do something useful. It works.

Sat Apr 29 12:31:56 MET DST 1995
* FLOW_* bug in testing the kind.

Sun Apr  9 23:10:30 MET DST 1995
* Erased the savetty from line_manage code. We can't reset the fd
  before close because it is alredy set up to work well.
* new function close_nohangup(fd) to close the modem fd without hangup the
  modem connection.

Wed Jan  4 16:02:12 MET 1995
* New functions:
  hangup_nodev() if mdmopendevice is NULL.
  getopenmodem() to get the struct modems structure of the currently opened
  modem.
* Some new error checking with line. Now you have to use a cua line. The
  library force you to use it even if you have specified a ttyS line. This
  is okay because we are a callout and callouts are cua ones.

Mon Jan  2 20:11:30 MET 1995
* prepared libmodem for release.

Fri Dec 23 10:37:59 MET 1994
* libmodem is now a separate package.
* added an MDMERROR for when the modem return ERROR
* now dial and bdial scans all the modem lines until found a free line.
* no more CLOCAL in line setup.
* new file: mdmlog.c, new routines for syslog.

Sun Dec  4 14:41:59 MET 1994
* First tries of libmodem.
* New management of open() with longjump and alarm
* debugging: libmodem now works quite well.

Sun Nov  6 16:45:29 MET 1994
* libmodem.a:
  The End.
  Debugging.

Sun Nov  6 00:10:21 MET 1994
* libmodem.a:
  written down near all the management functions. Mainly open,
  line setup, modem initialization and modem dialing.

Sat Nov  5 00:10:50 MET 1994
* Continue the libmodem.a
  Ended the configuration file section.
  written down a starting point for mdmerrno.
  Started low level routines (dial/undial/hangup)

Fri Nov  4 00:06:13 MET 1994
* libmodemcap definitely out.
* written down the basis of a library of modem management. The modems
  configuration will be in /etc/modems and there will be all the characteristics
  of modems. This library will be a front-end for the programmer.
  There will be exported functions like:

  int fd = dial(char *phonenum)
  int fd = ldial (char *phonenum, char *line)
  int fd = bdial( char *phonenum, int baud)
  int fd = bldial(char *phonenum, char *line, int baud)
