6300+ Monochrome Mode

Does anyone know how I get an AT&T 6300 Plus with a color monitor to go
into monochrome mode?  

The System Programmer's Guide talks about ROM BIOS routines (INT 10H)
that mess with the video attributes.  The parameters I apparently need
to use are AH=0 and AL=0.  The "AL=0" tells the video controller to use
40 x 25 monochrome text mode.

This seems to be what I need to use, but I have no idea what to do with
these parameters.  Do I have to write some kind of assembly language
program (I've never done that!), or is there a way I can get into this
mode from DOS?  Also, is there a way I could go into this mode auto-
matically (like during the startup of a communications package) and then
resume the original mode later?

Any help would be highly appreciated.
