#GPFax wont Recieve

>> What is your init string in GPFax? And did you select the USR or the generic
class 1 setting?
My init string is the default that came with the program and it is set to USR
modem.
–> ATE0V1X4&D2S0=0&H2&B1
I have the modem DIP Sw set to auto answer and the auto answer light is on
untill I start GPFax then it goes out. I've tried it in AA off – same. I'm
curious about S0=0 in the init string, according to the USR book this disables
AA. But the option screen gives me a choice of Auto Answer or not. I called USR
and the guy who answered told me I need a special modem cable that supports
Hardware Handshaking/Hardware Flow Control, but no one I talked to here knows
of a difference in modem cables — is there a difference?? All the computer
stores up here treat me like a leper or something when I mention that I have a
superior Amiga.:) I've tried lower my standards and telling them I use IBM, but
then they start asking questions about UARTS and things.

George,
Turn off AutoAnswer by having the S0=0 and the having the DIP switch off. This
turns off AutoAnswer on the modem, but GPFax takes care of picking up the phone
line. The setting in GPFax specifies software handshaking (XON/XOFF), so you
want to make sure that your Prefs/Serial selection is set to XON/XOFF. I would
recommend using RTS/CTS (hardware flow control) when using a high-speed modem.
You will need to do the following:
1) Change your init string's &H2 to &H1 (this enables RTS/CTS flow control) 2)
Change the Prefs/Serial to RTS/CTS 8N1 and alteast have a baud rate of
19200 for a 14.4 or 31250 for a 28.8 model 3) Get a hardware flow-control
cable (also knows as a 7-wire cable or
as a straight through serial cable)
Hopefully, things should be working a bit better for you then. If you go to a
PC store and they ask what type of UART chip, say you have a 16550 (16-bit)
UART and that should take care of them. You actually don't have a 16550, but a
UART is built into one of the custom chips (Denise, if I'm not mistaked). The
UART controls Serial I/O functions.

Christian;
I tried some of your ideas about changing the INIT string and checking
prefs/serial. I've got the modem working good in DATA mode now, both send and
recieve. I havent had a chance to try recieve FAXS yet though.
YOu said try using RTS/CTS and changing init string from &H2 to &H1. This is
the default in the modem so I dont need this in the INIT string, or do I??
Another thing you said is to get a hardware flow control cable. How do I know
what I have is or isnt this type. When I bought the cable it said MODEM Cable
on the package. Are there different types, I thought all modem cables were the
same.

George,
Glad to hear that your modem is working data wise pretty well now. How is it
doing sending faxes?
As for &H1, I would keep it in the init string. Some comm programs change the
modem's active profile and it they change it to &H2, then you could have some
problems with handshaking. I say keep it in there for good measure.
Well, you could test the cable lines to see if you have a hardware handshaking
cable. Or you could ask the people you bought the cable from. They're are
three general categories on modem cables. 1) Standard Hayes cable – your normal
type 2) Hardware handshaking cable (7-wire or straight through) – has wiring to
control the RTS/CTS lines need for hardware handshaking 3) Null modem cable –
changes the transmit and receive positions on the cable between connectors.
Okay for connecting two computers through serial ports, but not good for
modems.
