5. Defining a Visible Bell You can add the entry for the vb capability in your own termcap file, if it doesn't already define one. Dennis Henriksen (duke@diku.dk) suggested to insert the following line in the termcap entry for linux (note that the entry is called console in old distributions): :vb=\E7\E[?5h\E[?5l\E[?5h\E[?5l\E[?5h\E[?5l\E[?5h\E[?5l\E8:\ The trailing backslash is used to escape the newline in the database. Dennis' code does the following (his own words): Save the cursor position (uust a safety precaution). Change the background color several times between normal and reverse. Restore the cursor position.
