Chapter 3 - Configuration
3.4.1 Changing Default Parameters
The default values for the other parameters in modem configuration menus
rarely need changing. They typically include the dialing prefix (ATDT for
touch-tone service and ATDP for rotary service), the dialing suffix (^M), the
hang-up string (+++ATH0^M), and response messages (RING, NO
CARRIER, BUSY, etc.). Communications software with a host mode might
also include an auto-answer string (AT S0=1^M).
3.5 Macintosh Initialization
Macintosh computers cannot use RTS/CTS hardware flow control without a
serial cable wired for hardware control. The Macintosh 128 and 512
models cannot use RTS/CTS flow control at all. For those Macintoshes
turn off the default RTS/CTS hardware flow control, turn on XON/XOFF
flow control and pacing, and ignore DTR:
AT &F X4 &E5 &E13 &D0 ^M
For hardware flow control, use the following initialization string:
AT &F X4 &E13 &D0 ^M
Add S0=0 to both strings to disable auto-answer if the MT2834BR is on a
voice line.
You can store the initialization string in nonvolatile memory. With your
communications software open and connected to the modem’s COM port,
type the initialization string in the terminal window, substituting a carriage
return for ^M. To store the string, enter
AT &F9 &W0 <CR>.
Now you can initialize your modem with the following simple string:
AT Z ^M
