;       Filename: hayes24.mdm
;       Date    : March 21, 1990
;       Script  : Standard script file for Hayes 2400 bps modems
;
;     This script file contains the standard modem setup strings used
;  by the External, Transmit and Listen programs. There are five
;  procedures defined in this script file for setting up the modem and
;  for connecting to a remote External machine.
;
;     The modem setup strings used here will be adequate for most
;  people but there may be some changes required if you are dialing
;  overseas and require a longer wait for Carrier Detect (S7 register)
;  or if you wish to change the speaker volume. Note that if you used
;  the -Innn option in version 1.0 or 2.0 that you will have to modify
;  the S7 register and recompile this script file.
;
;     Consult your modem manual for more information on setup options.
;
;  Script procedures defined:
;       INITIALIZE
;       RESET
;       CALL
;       ANSWER
;       DISCONNECT
;
;  Return codes for External, Transmit, Listen:
;       0  - OK
;       1  - CONNECT 300
;       2  - not defined
;       3  - NO CARRIER
;       4  - ERROR
;       5  - CONNECT 1200
;       6  - not defined
;       7  - BUSY
;       8  - NO ANSWER
;       9  - not defined
