Well, if you're one of the lucky stiffs that has purchased a new
SupraFaxModem in the last month or two, you're no doubt itching to do
that first download at 14400 baud. Problem is, if you're like the
average SupraFaxModem buyer, you've exactly ZERO experience setting up
these things. What this text file is intended to do is to get you up
and flying with your new modem.
This file is divided into five sections:
1. Modem NRam settings.
2. JRComm settings.
3. NComm settings.
4. Term settings.
5. TrapDoor settings.
6. Serial Prefs settings.
1. Modem NRam settings.
No matter what term program you use, you can program your modem
directly from the terminal program's screen. Once you've plugged
in all of the values needed, you can then save them off into the
modem's NRam and simply call them back using ATZ0 or Z1.
Programming the modem is accomplished by typing in a series of AT
commands. In the following text, you must prefix all strings with
the AT (Hayes command set) designation, which will get the modem's
attention and tell it that what follows is a command. For
instance, "V1" would mean that you type in ATV1 and then hit
return, and hope the modem says "OK" back at you.
OK, here's a brief breakdown:
E1 Enables the modem to echo back the commands you send.
Lx Set this wherever you like. It is the speaker volume,
which can be any number from 0 (low) to 3 (high).
Mx If x is 0, the speaker will always be off. If you want to
hear the phone lines while dialing, use M1.
N1 Tells the modem to connect at the highest possible speed.
Q0 Tells the modem to send results back to the computer.
V1 Tells the modem to use verbose (wordy) result codes.
W2 Tells the modem to report the actual connect speed to the
computer. IMPORTANT!!! If you leave W set at 0, and use
TrapDoor, your users will get massive download errors!
X4 Waits for dial tone before dialing; reports CONNECT XXXX
&C1 DataCarrierDetect line from modem only on when another
modem is connected.
&D2 Disconnects when Data Terminal Ready (TR light) is off
&K3 Enables hardware flow control between the computer and the
modem. Make sure Serial prefs and software is configured
for this.
&Q5 Enables Asynchronous Reliable mode. Modem will attempt
the best speed/reliability connection possible.
&R0 Makes CTS respond to RTS in hardware handshaking.
\N3 Autoreliable mode is ON.
%C1 Enable compression.
*H Negotiate connection at highest speed possible.
After programming all of this in (and assuming you haven't changed
anything else), you should be ready to go. Type AT&W0 or &W1 to
save your new configuration in NRam location 0 or 1. Now, to
initialize your modem, all you need to do is send ATZ0 or Z1
(depending on which location you stored the settings at) and your
modem will come up ready to blaze!
2. JRComm 1.02a settings.
JRComm can be set up from either JR-Edit or from JR-Comm itself.
Either way, the same menu options are available. Once your modem
is set up, you need to make sure the following things are set up
right with JRComm.
General Serial Port menu option:
Make SURE that XOn/XOff is deselected. Also, it is wise to have
the baud setting at 2400 unless ALL boards you call are at least
v.32 boards. But usually it is a good idea to have the default
at lower speeds and set the BBS's that have high speed modems to
the appropriate speed.
General MODEM menu option:
Init Command: Set to either ATZ0^M or ATZ1^M, depending on
where your settings were stored.
Hangup Command: Set to ~~~+++~~~ATH0^M .
Dial Prefix: Set to ATDT or ATDP, depending if you have
pulse or tone dialing available.
Dial Postfix: Set to ^M.
Dial Timeout: Set to 60. This determines how long your
modem can attempt to negotiate a link before
JRComm gives up and hangs up. Normally, with
a 2400 baud modem, the negotiating session was
short. But, with more capability comes more
complexity in the connection. If you do not
have this set to long enough a period, you
will have trouble with connects to many high
speed systems, especially those that use older
modems.
Drop DTR Set this to ON.
Dialer Auto-baud Set this to ON.
General Parameters:
Set RTS/CTS handshaking to ON.
Don't forget to edit your phonebook entries, as well, along the
same lines.
3. NComm 2.0 settings.
COM: HANDSHAKING:
Set to RTS/CTS
PHONE: MODEM SETUP:
Init String: Set to either ATZ0\n or ATZ1\n, depending on
where your settings were stored.
Locked Rate: Set this to ON.
DTR-Hangup Set this to ON.
4. TERM 2.1 settings.
Once your modem is set up, you need to make sure the following
things are set up right with JRComm.
Preferences: Serial:
BAUD RATE Slider as high as possible.
HANDSHAKING = RTS/CTS
Preferences: MODEM:
Modem Init String: Set to either ATZ0\r or ATZ1\r, depending on
where your settings were stored.
Hangup Command: ~~~~~~~~~ATH0\r .
Dial Prefix: Set to ATDT or ATDP, depending if you have
pulse or tone dialing available.
Dialer Auto-baud Set this to ON.
Drop DTR Set this to ON.
Dial Timeout: 1.00 Min
Don't forget to edit your phonebook entries, as well, along the
same lines.
5. TrapDoor settings.
Unless you're running a BBS or point, you shouldn't need to mess
with TrapDoor. In the event you do, here are the TrapDoor.cfg
parameters you need to look at.
BAUD 19200 (or whatever your serial prefs can support)
LOCK
MINBAUD 300 (or whatever)
NOMAXBAUD
SNIFFARQ
SLOWMODEM 8 (may need tweaking, but 8 works great here)
MODEMINIT "~~AT~Z0~~|~~" (or AT~Z1)
MODEMHANGUP "^|^"
MODEMDIALPRE "~~AT~DT"
MODEMDIALPOST "|"
SHARED (maybe)
DSR <== these two are IMPORTANT
7WIRE <==
ADJUST 0 (see SlowModem)
NOSWEPULSE
6. Serial Prefs:
Two things to look at in your Serial Prefs. One, you should have
RTS/CTS handshaking enabled, and two, you should have your baud
rate set as high as your serial port supports.
Afterword:
I'm no expert with these things. However, I have tested the
SupraFaxModem with all of the mentioned programs, with good
results, with the remote modem being both Supra and DST. My best
CPS to date is with a DST using Trapdoor, where I get 1600-1700
routinely.
If you spot something to tweak the modem/program even higher,
please let me know so I can add it here.
Happy modeming!
