║ GT-Help Configuration │ Quattrocard SB2422PC ║
╟───────────────────────┴────────────────────────────────────╢
║ created by Harry Green (050/003) June 1990 ║
╚════════════════════════════════════════════════════════════╝
This configuration operates using Fixed DTE rate - which is necessary
to support V23.
Answering is controlled solely by GT (ie, S0=0 at all times).
This ensures that the modem does not answer calls at unwanted times.
The setup leaves the modem in "MNP-optional" (&E4) mode, ie a MNP
connection will be established if the remote end supports it,
otherwise a non-MNP connection will be established. &E4 mode is
not documented in the manual, but works - though it might not on
older quattrocards.
Assumptions:
-----------
This configuration assumes nothing except the AT&F defaults.
You could reduce the length of the terminal mode INIT string by
putting some information in non-volatile RAM. The easy way to
do this -- when you are sure the configuration is working correctly
- is :
a) go freshly into terminal mode (so the init string's already
in the modem's working RAM
b) issue the command AT&W|
c) change the terminal mode INIT string to ATZ|
Of course, this will *only* save a couple of seconds in
initialising - no need to do this if you're happy as it stands.
Customising
-----------
When used with GT-Help, all non-indented lines are copied to the GT-CNF
file. So if editing, be sure to keep comments and commands suitably
distinguished in this way.
-------------------------------------------------------------------
Fixed DTE rate ?
FD=TRUE
-------------------------------------------------------------------
BA= Default Baud Rate.
BA=2400
-------------------------------------------------------------------
MB= Maximum Baud Rate. Allows you to put 9600 in phone directory
in case you get something better later.
MB=2400
-------------------------------------------------------------------
CS= Honor CTS from modem option. *Needed* for fixed DTE rate.
CS=TRUE
-------------------------------------------------------------------
Non-hayes setups. Not applicable - leave them present but empty to ensure
any old contents are properly overwritten when transferred to GT.CNF.

-------------------------------------------------------------------
Standard Dialling Prefix. You will want to change this to ATTD if
your phone line and modem both support tone dialling.
PR=ATPD
-------------------------------------------------------------------
PO= Dialing Post String, use the | character where a Return is
required.
PO=|
-------------------------------------------------------------------
HU= The modem hang-up string. Normally keep it *empty* (DTR control).
HU=
-------------------------------------------------------------------
MI= Modem initialization string :
- - - line length limit - - - - - - - ──┐
│
MI=~AT&F&C1&D3&E4&I1&K2X6S0=0S10=35|
&F ensures we start from a well-defined state - the factory
defaults.
&C1 is important - prevents modem from pretending there's a
carrier when there isn't.
&D3 ensures modem disconnects and is reset whenever DTR is dropped
&E4 enables MNP error correction
&I1 enables constant speed interface (connect message showing
line speed)
&K2 enables hardware (CTS) flow control
X6 all response codes enabled
S0=0 takes modem out of autoanswer mode
S10=35 keep online until carrier lost for more than about
3 seconds
-------------------------------------------------------------------
HO= Host mode, modem initialization string.
HO=~ATS2=255 S10=25|
S2=255 stops command mode if user types +++
S10=25 slightly tighter carrier monitoring when in host
-------------------------------------------------------------------
AS= Answer string.
AS=~ATA|
-------------------------------------------------------------------
SY= Speaker command for initial dialling (change to M0 for speaker off)
SY=~ATM1|
-------------------------------------------------------------------
SN= Speaker command for repeat dialling (change to M0 for speaker off)
SN=~ATM1|
-------------------------------------------------------------------
FC= Forced Carrier. You definitely don't want this.
FC=FALSE
-------------------------------------------------------------------
RC= Result codes.
They are slightly different from what is documented - I have never
seen a /NO ARQ suffix! Also, 1200 baud connects with SPAR correction
will be logged as 4800 baud calls - there just isn't room elswhere.
RC=0,OK,Trying to connect:-
RC=1,CONNECT 300,CONNECT 300/REL
RC=2,RING
RC=3,NO CARRIER,(Timeout),(Aborted!)
RC=4,ERROR
RC=5,CONNECT 1200,CONNECT 1275
RC=6,NO DIALTONE
RC=7,BUSY
RC=8,NO ANSWER,BLACKLISTED
RC=9
RC=10,CONNECT 2400
RC=11,
RC=12,
RC=13,CONNECT 9600
RC=14,CONNECT 1200/ARQ ON,CONNECT 1275/ARQ ON
RC=15,CONNECT 1200/REL,CONNECT 1275/REL
RC=16,CONNECT 2400/REL,CONNECT 2400/ARQ ON
RC=17,
RC=18,
RC=19,
-------------------------------------------------------------------
HN= Off-hook string. Sent to modem when the sysop logs on to GT locally.
Often used to make it go off-hook, though its not compulsory.
HN=~ATH1|
-------------------------------------------------------------------
HY= On-hook string. Sent to modem when sysop logs off after local use
HY=~ATH0|
