Apple Express Fax/Modem - Manual (Page 132)

! Flash This modifier causes the modem to go on-hook then back
off-hook, as if the receiver on the telephone set had been pressed
momentarily. This modifier can be placed anywhere in the dial
string.
R Reverse mode The R modifier changes the modem from originate
mode to answer mode once the dialing process has been
completed. This command is used only at the end of the dial
string.
This modifier is used for compatibility with old originate-only
modems.
; Return to local command state after dialing The semicolon (;)
modifier may be put at the end of the dialing command. It forces
the modem back to the local command state after dialing a
number. The modem does not attempt a connection. This allows
you to use the modem as a dialer (you must pick up the telephone
handset at the end of the dial command) or dialing numbers in two
or more steps.
S= n Dial telephone number stored at location n Dials telephone number
stored in location n, where n is 0, 1, or 2. You must have
previously saved the value with the AT&Z command.
L Dial last telephone number Redials the last number dialed when
placed after the D command.
E n Echo off/on When the echo is turned on, the characters sent to the
modem in command state are echoed back by the modem to the
host computer. The E command is functional only when the
modem is in command state.
0 Turns off the echo command.
1 Turns on the echo command. This allows you to see that
characters you have sent to the modem have been received and sent
back.
