For applications which generate FS files, the pages and begin_page parameters of the $fax_filename command may be used to specify a partial transmission of the document. This selection of pages from the document is processed independently of the partial retry logic. The selection of pages from a multiple-page TIFF file is currently only possible with the Dialogic FAX40 (VFX/40) and JCT boards and with Brooktrout fax boards.
