3.8 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 modem 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
