USRobotics 3453C modem Terminal Interface issue

[Samantha99224]

I just got a USRobotics 3453 C Courier business Modem.

It is connected to my PC by the Serial Com Port.

I am using Putty as the terminal software. I configured Putty with the settings in the USRobotics installation file:

Standard COM
port settings are:

bits per second: 115,200

data bits: 8;

parity: none;

stop bits:1;

flow control: hardware

The hardware setting is weird In putty there is :

XON/XOFF

RTS/CTS

AND

DSR/DTR

I tried all three of them.

Putty opens up and then I see a cursor, but you cannot type anything.
It is just a static cursor.

But I know the modem sees data, because when I open putty and load the session; the lights on the front of the modem change.
I cannot even begin to configure the modem until I can get to where I can type. Please help me if you can.

Thanks.
