Actually, the command string 'ATDT 5551234' (some modems require upper 
case commands, most don't these days) is a bit more complex than you 
realize, Thom.  The first two characters, 'AT' are used to get the 
modem's "ATtention" so it can treat the rest of the string as a command. 
The next character, 'D', puts the modem into the "Dial" mode.  At this 
point, the modem expects to see a string of characters (and subcommands) 
to use while dialing.  The subcommands you are likely to use are:
 
   T - Tone (DTMF) dial
   P - Pulse dial
   , - Pause for (default) 2 seconds
 
Hence, to dial an 800 number you might enter 'ATDT18001234567<CR>'
or, since the space and dash are ignored 'ATDT 1-800-123-4567<CR>'.
 
Now, if you were to call from an office location that did NOT support 
"Touch-Tone(tm)" calling, but you needed touch-tone to access the 800 
number, and you needed to dial 99 to get to the outside phone system, 
you would have to select pulse dial, dial th 99, change to tone dial, 
wait to get the outside line, then dial as before.  The command might 
look like this:
    
   'ATDP 99, T1-800-123-4567<CR>'
              ~~~~~~~~~~~~~~
    ~~|| ~~| | \_Number to dial

Hope this clears things up a bit.  Most of this should really be covered 
in your MODEM manual, not the manual that comes (or didn't come) with 
the terminal program you are using.
