1.4 The Serial Port and Interrupt of the Modem Card Each peripheral device, such as a modem, uses a port that is either serial or parallel, depending on its design. Each port can only accept one device; otherwise, there is a conflict. Your modem is designed for use with serial ports. You can use any COM port, COM1 to COM4. Some computers, may support only two serial ports. See your computer manual for the number of ports on your computer. Computers use interrupts (IRQ) to control the d

Install the modem into your computer as follows. 1) Turn off the computer 2) Remove the cover of your computer and locate the 5614HP expansion slot. Refer to your computer installation guide. 3) Plug in your 5614HP modem to the expansion slot, and make sure the connectors of the modem card are exactly aligned with the expansion slot. 4) Secure the modem card to the computer with screw. 5) Connect the telephone line from the wall outlet to the jack labeled LINE. 6) Connect the line fr

the popular communications software packages work with your modem. If you have any problem using the software, please contact your software dealer, publisher, or modem dealer. To install the software, turn on your computer and modem, and boot the communications software. Follow the software manual instructions to execute software installation. Software configuration procedures vary with each software prog- ram, computer, and application. Refer to your software manual for more informatio

Most popular communication software packages allow users to specify a command string and the dialing prefix that is sent to the modem prior to dialing telephone number digits. The dialing prefix reconfigures the modem according to your commands. Below are some examples of a dialing prefix string: ATS0=3 Instructs the modem to auto-answer an incoming call on the third ring. ATX4DT9W Instructs the modem to first tone-dial the number 9 and hold it until a dial tone is detected. AT

Chapter 2 Modem Fundamentals This chapter provides a brief overview of how modems work. 2.1 Modem Basics Modems let computers communicate with other computers using normal telephone lines or leased lines. Your modem sends communications by modulating (converting) data into sound waves that a telephone can transmit and another modem can receive. Your modem receives communications by demodulating sound waves from the telephone into data your computer can recognize. The term modem is a

For 1200bps protocols, the Bell standard is used mainly in the United States and Canada, while the CCITT standard is used in most other countries. For 2400bps and faster protocols, the CCITT standards are used internationally. Th

communicate with both the remote modem and local computer, through the telephone line and serial port cable, respectively. Figure 1-1 describes the DCE speed relationship between modems. The speed over the telephone line at which your modem communicates with the remote modem is called the on-line speed. Since the modem is Data Communications Equipment, the communications speed is called the DCE speed. On the other hand, the speed over the serial port at which your modem communicates w

However, in a reliable link or a direct link the baud rate adjustment capability may be disabled, so that the serial port speed may be different to the on-line speed. If data comes in faster than it goes out, the faster incoming data is stored in the data buffer. Therefore, when flow control capability is enabled, it is advisable that the on-line (DCE) speed be at a rate equal to or higher than the serial (DTE) port speed. Otherwise, data may be lost after the buffer is full. 2.7 Error

supports MNP5, the connection can only be established in MNP5 mode. You should use the V.42bis recommendations as long as the on- line modem at the remote end supports the same. This way, you can achieve higher data throughput. To select the ECDC mode, use the command \N. 2.8 Flow Control While on-line, your modem is between your computer and the remote modem (or the remote computer, if you consider the remote modem as a transparent device). Your modem communicates with your computer

The NVRAM does not require a back up battery so that you can eliminate the threat of data loss due to a dead battery, as well as avoid hardware damage due to electrolyte leakage. 2.10 Factory Default Profile (FDP) The FDP is the default configuration profile stored in your modem read-only memory (ROM), which can not be modified by the user. The FDP is intended for rescuing the modem in case the user misconfigures the modem settings. To display the FDP, use command &F to place the profi

When the modem is turned on or reset by command ATZ, the ACA is first loaded with the FDP, and then is overwritten by the major SCP. The commands you issue to the modem actually change the contents of the ACA. However, once the modem is turned off, all the settings in the ACA vanish. To save the current ACA configuration to a SCP for further use, issue command &W followed with the number of the SCP. For example, issue &W1 saves the current configuration to SCP1. The next time you want

Chapter 3 Modem Operation and Response Codes This chapter describes modem states, commands and response codes and explains how to issue commands to the modem. 3.1 Command State and Data State During operation, your modem is either in command state or data state. The figure below shows the relationships between the two states and how to enter and abort from each of them. In command state, the modem interprets all the characters it receives as commands. The command state may either be o

different one by assigning the ASCII value (in decimal) of the new escape character to register S2. 3.3 Issuing Commands When the modem is in command state, you can issue commands to the modem by typing them on the keyboard. A command line shall always begin with AT (or at), followed by the command or commands, and completed with a return key. The only exception is A/, which does not require the AT prefix and a return key. Some commands, such as M1, M2 or M3, require a parameter after

ATS5=27 designates ESC as the backspace character. 3.6 Modem AT Response Codes Unless you have instructed the modem not to send response codes by issuing command Q1, it will always send a response code after executing a command line. The response code can be displayed in word or in digit form depending on the V command issued. Command X0 to X4 lets you select different response sets of the modem, which enables or disables certain response codes. In general application, you can select
