16. Troubleshooting

In order to obtain more information from faxmaster on what happens while the program is being run, you can start faxmaster with the parameter -debug. Then a little more detailed information is written on the screen while the program is being run. Also look in the log files under ETCDIR/Log for the respective command. Interesting information can be found there if something has gone wrong.

If there is a problem with the modem, you can see if it is possible to call out by using the normal UNIX command cu. If you get the fault code NOAN (no answer) or NODT (no dialtone) you can try with a normal telephone in the jack to see if you get a tone and can ring the recipient's fax using this to check that it is actually answering.

It is possible to use the system if you are logged in as super-user (root), but not otherwise

This is most probably a problem with regard to authority. Go through the various files and libraries which XFAX uses and check the owner and rights.

Converting a fax is not successful

Are the typeface files in the right place, unpacked and with the right authority?

The program looks for files by looking at what FONTDIR is set at in the configuration file.

In the delivery medium the files are packed with the UNIX command compress. The file name then ends with a "Z". The files should be unpacked during installation. If it has not been possible to do this, it should be done manually by going into the directory where the files are located and writing compress -d *.

All users must have the right to read typeface files and to read and search in the directory where they are located.

When I start faxmaster I obtain the message: Faxmaster is already running, although it unquestionably is not. Why?

Faxmaster creates a locking file, /tmp/LCK.faxmaster, when it starts up which should be removed automatically when faxmaster terminates. If faxmaster is killed with kill -9 or is terminated in some other unconventional way the locking file may remain. Remove this with rm /tmp/LCK.faxmaster and try again. Note. Faxmaster should not be killed with kill -9. Instead, use signal 15 that is the standard value for kill.

Faxmaster does not send a fax that is in a queue to be sent. The status is PE.

Check whether there is a locking file for the port under /usr/spool/uucp, /var/spool/locks or another directory depending on the operative system, the name of the file begins with LCK, in SCO this is called e.g. LCL..ttyxx. If such a file exists and no program uses the port, remove the locking file with rm. With locked files each program writes its process-id, as ASCII or binary. Again depending on the operative system.

There is a problem when sending a fax abroad

Do you use Tele2 and dial 007 instead of 009? Ensure that the line the modem is connected to is registered with Tele2.

Transmission of faxes is often broken off before they are finished or there are lines missing in the middle of a fax.

This is probably a problem of flow control. Depending on the type of modem and the serial ports in the computer, sometimes software and other times hardware flow control should be used. Begin by setting up the system for XON/XOFF. This is generally the easiest way to get started.

In order to run RTS/CTS flow control, an initiation string should be used which sets up the modem for RTS/CTS. In addition, it is necessary that the serial port is set up for, and can handle, RTS/CTS. This method is to be preferred but is not supported by all serial cards.

There is a problem with sending a fax on HP-UX.

The program is compiled on a HP 9000/712 and as standard tries to set up hardware flow control. This is not always so satisfactory on HP's server machines. Therefore you can shut off "the hardware control attempt" by adding FLOW = 0 in the configuration file.
