The second edition of the DOS PROGRAMMER'S REFERENCE 
                           (QUE Programming series)
contains good documentation of these and other "undocumented"
interupts and functions.

Make sure you look at the second edition, the first was 
not worth buying.

from the book -  	
	"Int 2Fh Multiplex Service Interrupt
	
	Multiplex service, only partially documented. 
	Controlled by content of AH register at entry, 
	which may range from 01 through FFh. 

	Comments: Only Function 12h, DOS internal services,
	is present in "vanilla" DOS operation; additional 
	functions graft themselves into this service when
	the corresponding program is installed.  For example,
	Function 01 has no meaning unless the resident portion
	of the DOS print spooler (PRINT.COM) has been installed."

etc, etc....

there are functions for assorted I/O and other utility functions:
	
	Function 12h Subfunction 05h - output a character
	Function 12h Subfunction 04h - normalize path separator
	Function 12h Subfunction 07h - move disk buffer  
	Function 12h Subfunction 0Ch - IOCTL open used by DOS

It is definatly a book worth having.

Just my opinion - I am in no way associated with the publisher.
