Version 0.6.0 and up support adding a user comment to faxes (in both sent and received tables).
If the read/unread state is saved in a database table (as described in Setting up YajHFC for small workgroups), this table needs 2 new columns where this comment can be saved.
In the options dialog go to the Modems panel for the desired server.
Check the Use the following list of modems option.
Add/Modify/Remove the modems in the table as you like.
For example: Enter the description "Company X" for the Modem with HylaFAX name "ttyS0".
To add a modem group here, add a new line to the table and enter the group's name as defined in the HylaFAX configuration as HylaFAX name (similar to the predefined any modem).
Click OK. You should now be able to see the modems you have defined in the modem selection list of the send dialog.
