Initiation string for ZFM5620-CF?

Is the battery and terminals good. Do the lights come on?

Instructions

1. • 1 Check which communication port and interrupt your modem is set to use. Typically, these are hard-wired selections on the board itself. Changing the jumpers on the board changes the port address and interrupt number. You must give forethought to the consequences of the decision. There are only two interrupt lines usable and four port addresses that are possible. Only one port can utilize an interrupt number at a time.
     
   • 2 Change the port and interrupt assignment if required. Restart your system and see if this solves the problems. If not, find the documentation for your modem. You must now generate the proper initialization string for your modem to maximize your communications. Some of the settings in the initialization string determine the audible sound of the modem when dialing and connecting. More important settings have to do with number of rings to wait before hanging up, time to wait between redials, sensitivity of the modem to line noise and enabling or disabling the transfer mode of X2 or V.90 (the two formats for 56K communication).
     
   • 3 Find the modem driver that you are using and check that it is the correct driver. There are many drivers available based on manufacturer and model of the modem. Not only is the driver modem specific but also the recommended initialization string. Make sure your modem receives the correct initialization string in the setup file or preference window in the application that uses the modem.
     

Configuration/Initialization String
Using a straight through cable and a PC or dumb terminal, enter the following string into the modem.

type in: at <cr>
modem responds with:OK
type in: at&F &B1 &A3 &I3 &S1 S13=1 &W0
modem responds with: OK

The current copper wired telephone lines are limited only to about 53K. If you are connected only to 33.6 or 28.8K, check the following first:Is your modem compatible with the modem used at your ISP? 
Is your modem set up to run at full speed? 
What's the maximum speed your ISP allows? 
How far away are you from your ISP? 
Some modems need special initiation strings to get full speed. 
Some conditions are out of your control, such as weather and conditions of the telephone lines in your community. 
Problems may occur when you are dialing through a phone system such as one in a hotel.
Modem answers incoming calls and then returns to the on-hook condition, disconnecting the caller: 
This occurs most often when connecting to a UNIX system. In most case, the host does not prefer to see any result or command echo codes. If this is the case, the codes can be disabled by adding E0 Q1 to the modem configuration string.

The modem dials and appears to complete the connection, but the communications software does not enter the correct mode. (The screen remains blank) 
This is normally caused by an I/O address or IRQ conflict. Verify that the COM port is not in use by any other serial device and if necessary use another COM port or I/O address settting. Refer to your computer manual on how to determine what serial ports are installed.

The modem dials and appears to complete the connection, but the communications software does not enter the correct mode. (The screen remains blank) 
There may be an I/O conflict (see the solution for the previous problem). 
The Result Codes may have been disabled by the software configuration set up. Check if Q1 is in the configuration or initialization string. If so, change it to Q0. 
Your software may require numeric result codes rather than verbal result codes. Use either V0 for numeric result codes or V1 for verbal result codes in your initiazation or configuration string. 
Some software require full extended result codes (i.e., CONNECT 33600 instead of CONNECT). This can be controlled by the Xn command. X0 sends a summarized code (CONNECT) and X4 sends a full extended code (CONNECT 33600) 
The modem does not auto answer
The auto answer mode is determined by the S0 register. If S0 has been set to 0, the modem will not answer. Asign another value to S0 by entering the following command: S0=n, where n = the number of rings to occur before the call is answered (ATS0=2, the modem answers after two rings)

The modem always answers the phone. 
Set the S0 register to 0. ATS0=0.

The communications software displays, "No Dialtone." 
Make sure that your phone cable is working properly and that it is firmly seated to the phone socket at your phone jack and in the real panel of the modem.

A high pitched squeal is emitted from the external speakers 
This phenomenon is "feedback" and occurs when the microphone is pointed at the external speaker or is close enough to pick up the speaker output. This may be remedied by using a unidirectional microphone, making sure that it is pointed away and as far from the speaker as functionally possible. Another option is to use a headset with an attached microphone.

Hi,

There are a couple of versions for the Compaq Presario notebook C791TU.

• Initially, pls go here. In #2 "Enter a product number" pls type Presario C791TU and click GO or the double arrow right button; .
• Thereafter, on the next page, click on the "Software & Driver Downloads";
• new page, select your Operating System;
• next page click on the appropriate drivers.

Insome instances, a particular driver may not be available for aparticular operating system. A workaround is to get the chipset used bythat device and go to the manufacturer's website.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Hi, You can try & proceed to HP website (http://www.hp.com/) and go to the Software & Driver Downloads (left side near the bottom). You have to determine the specif model/version of your HP computer which might look something like "HP Pavilion 4550Z" From initial indications you would be looking for an Internal Modem/Sound Card that was originally set for Windows 98SE. Chances are that it is a Conexant or Rockwell SoftK56 Data,Fax PCI Modem, with Master Riptide PCI Audio Device. Post back should you need additional information. State your PC's model. Good luck and kind regards.
