You probably have already bee advised by computer literate type in your 
local, but if not, then I throw in a few ideas: the extension does not 
determine the chances of importing as much as the file format.  The format is 
the type and structure of the data in the file. For example the normal text 
file is a series of bytes where each byte will represent some character, the 
most universal is the ASCII standard which is the easiest to inport into ACAD 
or anything else.  Other text related formats exist
to achieve greater control of the end product and make the files useful to 
only that special product line, etc. The other format that you mentioned is 
the fax, of which there are at least 3 now. They all fall into the Raster 
based formats. Raster refers to the lines of dots, on paper, or pixels on 
screens. PCX and TIFF are reaster. acad exports 
raster and may import yours. Some fax can be converted to PCX and inported
as a maze of lines that looks something like the image but it is not imported 
as text or the acad entity call TEXT. There are programs that sometimes can 
recognize the text characters in certain raster files,
usually from a specific scanning device format. Hope that was on the wanted 
subject.
