This document is intended to describe the significant differences between hylafax-4.1.5 and older releases, point out any known incompatibilites and issues, and provide the reader with directions to further resources regarding HylaFAX.

  • sendfax warns when -d options are used poorly
  • NSF recognition on sending for virtually all US, UK, and Japan codes
  • DSO versioning follows HylaFAX
  • additional modem support for various USR, Digi, and Lucent/Agere modems
  • faxqclean now has a "force archiving" option
  • faxanswer supports Caller-ID now when faxgetty is running
  • removed support for Solaris DSOs and various other Solaris bugfixes
  • new Class1MsgRecvHack, Class1ResponseWaitCmd, and RingExtended config options
  • probemodem options to send one command and not kill faxgetty
  • improve the select bug workaround
  • faxq triggers LOCKWAIT explicitly when initiating faxsend
  • faxgetty polls for lockfiles while RUNNING
  • fix broken facsimile polling when in Class 1
Please refer to CHANGES for a detailed list of code changes


  • HylaFAX corrupts images received in 2D-MMR (patch available).
  • Specific support for fax class 1.0 is not yet implemented.
  • A low-priority job can block a high priority job to the same destination.
Please refer to HylaFAX Bugzilla for a detailed list of issues.


  • faxinfo from older installations of HylaFAX will not give correct output when run against newly received fax image files. faxinfo from 4.1.3 and later can read both newly received and older fax image files.
  • HylaFAX source needs to be extracted and built on a case-sensitive filesystem. Users with case-insensitive filesystems, such as those with Mac OS X HFS, will need to mount a new filesystem (i.e. UFS) for this purpose.
  • The popular faxrcvd-mail scripts have been deprecated by FILETYPE use in FaxDispatch, and unchanged, will not work with faxgetty in 4.1.3 and later. See 'man faxrcvd' for details.


Anyone running the short-lived 4.1.4 release of HylaFAX should consider this a mandatory upgrade. A race condition in the lockfile polling code could lead to a non-responsive faxgetty in some circumstances.

A large number of security fixes were included in the 4.1.3 release of HylaFAX which make it very important to upgrade to 4.1.3 or newer. If you are not already running 4.1.3, this 4.1.5 release is a recommended upgrade.

Anyone already running 4.1.3 on Solaris should also upgrade, since a number of Solaris-specific issues were addressed in this release.

Users who find that their modem status does not always return to idle after sending a fax, such as those with low-level select bugs or those running RedHat Linux 7.3, should upgrade.


Binary packages for some operating systems and platforms are available. Please see ftp://ftp.hylafax.org/binary/ and http://www.hylafax.org/howto/install.html#ss2.3.3 If you are able and willing to produce a binary package of HylaFAX for general distribution, then you are invited to join hylafax-devel@hylafax.org and solicit your binary package.
