#Where did they go?
17 messages in this thread
Hi ALL,
I have a problem I hope you can help me with. When I inter a message
base and try to READ ALL in capture mode, after a while, – 50 messages or
so- I start to lose parts of each message.
I am using an Amiga 1000 with a SupraFaxModem at 9600 Baud, Ncomm
software set to XON/XOFF. Any ideas ?
Edson
Edson,
Most of the high-speed modem vendors recommend using Hardware
handshaking (RTS/CTS) between your computer and modem, rather than
software handshaking (XON/XOFF). This is what I use with my PPI 14.4
modem and have no problems. I'm not familiar with NComm, and my Supra FAX
modem is in my other office (i.e., I don't have the docs handy), so I
can't give you any specifics about "set this here, etc.".
Hope this helps….

Hi Bob,
As I am using an Amiga 1000 I have a problem with the PIN OUTS in the
serial port IE. I can't just plug in the cable supplied with the modem. I
have left the cable from my old Amiga 1200 RS modem plugged into the serial
port and plugged the SupraFax into the existing cable. This means I only
have 7 PINS connected and I think (RTS/CTS) is not working.

I had the same trouble hooking up a Supra 2400 plus to my 1000. Get a
RS-232 jumper box, (Radio Shack has them). Hook up all the same pins that
are on the 1200, so all the same signals that are on the 1200 are passed.
Hook up pins 4 & 5 from the modem to 4 & 5 to the 1000. That is your RTS
(4) and CTS (5), my error correction will not work without it. With the
jumper box, you can use a standard cable, without worry of the +5v, +12v,
and -5v getting to the modem since they are not passed.

Hi Richard,
I have the SupraFax V.32 bis running through the PASS THROUGH of my old
Amiga 1200 RS modem -7 pin- Do you know if this correct ? Or are you saying
that PINS 4 and 5 have to be added ? If so could I not just cut the three
hot pins ( +5v, +12v, and -5v ) and use the standard cable? Would you
happen to know what the three HOT pins are?
Edson
PS: I think I have found the problem! Seems NComm does not inform the Modem
that (XON/XOFF) is set. When I start a capture with HANDSHAKING set to none
then -after 3 or 4 messages have scrolled by- turn on (XON/XOFF) everything
goes fine.
PPS: I thought AutoPilot needed workbench v2.0+. How are you using it?
Edson,
I tried the same thing, hooking up the Supra on the pass thru of the
1200 Amiga modem. I checked the 1680 manual and it does have pin 5
(Clear-to-Send), so it's just missing Request-to-Send (pin 4). This
signal is needed for anything except basic modems (no MNP, V.42bis,
V.32, V.32bis.). On the 1000 serial port pin #14 is -5 volts, pin #21
is +5 volts, and pin #23 is +12 volts. If you get the jumper box and
just jump the pins numbers 2,3,4,5,6,7,8,12,20,22.
As for running AutoPilot, my 1000 has a Rejuvenator with 2.04 ROM and
ECS Agnus and Denise, with a 25 mhz 68030/68882 MMR. It works great.

Hi Richard,
->I tried the same thing, hooking up the Supra – Etc.
Thanks very much for the info, I knew that my SupraFax modem was not
working to its full potential, but it was so much faster then the old 1200
that it didn't seem to matter. I will see about the jumper box after the
holidays, and will use your expertise to set it up.
All the Best for the Holidays

PS: Can you still call it an A1000? 😉
The problem is probably caused by the XON/XOFF. Change that to RTS/CTS
and see if things don't improve.

Hi Betty
>The problem is probably caused by the XON/XOFF.<
Using the PRACTICE FORUM as my benchmark, I have tried everything I can
think off. 2400 baud is no problem. At 9600 I have tried NO HANDSHAKING –
XON/XOFF – RTS/CTS – capture on to HD, RAM: and no capture. All to no
avail.
I don't think RTS/CTS works with my Amiga 1000 as I can not plug the
SurpraFax directly into the serial port. Some problem with the PIN OUTS I
have been told that 3 PINS have to be disconnected, but do not know which
3. So at present I am connected through the cable from my old Amiga 1200 RS
modem, that means only 7 PINS are being used.
One thing that does work, is when the messages start to scramble I
switch HANDSHAKING from XON/XOFF to NONE, and this clears the problem up
for a while, when it starts again I switch back to XON/XOFF.

An unaccelerated A1000 will have trouble keeping up with the data flow at
9600bps if there is much of ANYthing else going on, OR if it is also
trying to maintain an 8- or 16-color screen.
If you are calling a 9600bps node, and are getting a V.42/LAPM connection
(i.e., error correcting), then you KNOW that the data is getting as far as
your modem OK, it HAS to be a problem in the modem to computer link at
your end.
Your best bet, in the opinion of MANY of us here on the forum, would be to
download and try AutoPilot (AmigaVendor Library 9, AP.LHA). I am running
with CIS at 9600 bps regularly and "cleanly" on an unaccelerated A2000.
AutoPilot is a semi-automated Compuserve management program that lets you
do the "fast" stuff ON-line (downloading, uploading, gathering messages)
but the "slow" stuff OFF-line (reading messages, deciding which of the
gathered headers to mark for message retrieval).

Hi JimDoc,
My old 1-1/2 MEG A1000 will not support O/S 2.0 so I think this leaves
out the AutoPilot option. I think I have found the problem! Seems NComm
does not inform the Modem that (XON/XOFF) is set. When I start a capture
with HANDSHAKING set to none then -after 3 or 4 messages have scrolled by-
turn on (XON/XOFF) everything goes fine.
Edson
PS: Have you noticed that holding down the right mouse button stops CI$
from scrolling ?
Edson;
Holding down the right mouse button does not stop CIS but only stops
intuition from scrolling the screen (intentional).

Hi Bill,
Sorry, I ment to say "Stops the -Amiga- from scrolling"

Holding down the right mouse button does not "stop CIS from scrolling".
The right mouse button is the menu button — when it is held down it stops
your Amiga from scrolling — data is still coming into the serial port and
unless you have xon/xoff working properly you will overflow the input
buffer and lose text.

Check out WHAP! (WHP19H.LHA) in library 9 of Amigavendor. It will go
online and capture messages and build file catalogs for you. It does sound
like it's time for you to get a hard drive!
I see others have addressed the problem of RTS/CTS vs XON/OFF.
Hi Michael,
I have already tried WHAP! and put it aside for now. I have a 65 MEG
hard drive, and this does not seem to be the problem. I think I have found
the problem! Seems NComm does not inform the Modem that (XON/XOFF) is set.
When I start a capture with HANDSHAKING set to none then -after 3 or 4
messages have scrolled by- turn on (XON/XOFF) everything goes fine.
