Your modem takes advantage of the Windows interface and the capabilities of your notebook to achieve faster data transfers than a regular modem.
Various computer systems use different types of terminal emulation, such as IBM 3270, TTY, DEC, or ANSI. Contact the system operator of the host modem you are dialing into to determine the type of emulation to use for that connection. If the system operator is unkown, try using the ANSI terminal emulation protocol.
File transfer is the ability to transport files between two computers using two modems. The modems must use a file transfer protocol, which can correct errors in transmission and begin the file transfer process. Both modems must use the same file transfer protocol.
At the time you set up a file transfer, your communications software will prompt you to designate a file transfer protocol. The following table describes some of the most common protocols:
For the best results when sending or receiving a file, follow these basic rules:
|
CAUTION: When files are shared, the risk of getting a computer virus always exists. We recommend the use of virus scanning software to make sure the files you receive and send do not contain viruses. |
All communications software allows for automatic dialing. See your software documentation for instructions.
To manually dial another modem, go into Terminal mode in your communications software and enter ATDT followed by a space and the telephone number.
When dialing, enter the same information you would if you were calling someone on the phone. For example, when dialing long distance, prefix the phone number with a 1 and the area code. If you are dialing from a telephone system that requires a 9 for an outside line, insert a 9 before the telephone number. You will probably need to place a comma or two after the 9 (9,,) to allow enough pause time to access the outside line (each comma designates a two-second delay. See S8 in AT Commands).
A modem can answer a call in one of three ways: Host, auto-answer, or manual answer.
Host mode is a feature of the software, although it is not available in all communications software packages. Host mode allows the modem to answer the phone and place the caller into a "host" mode, allowing callers to download files, upload files, and chat with you while their modem is connected. Refer to your software documentation for instructions on how to use this feature.
Auto-answer is used to answer an incoming call without user intervention. The AT command for auto-answer is ATS=n, where n is the number of rings before the incoming call is answered. For example, ATS=2 tells the modem to answer after the second ring.
Manual answer tells the receiving modem not to answer when the phone rings. ATS must be set to 0 (ATS=0) when you are using manual answer. When the phone rings while you are in terminal mode in your communications software, the word RING will appear on the computer screen. You must then type ATA to tell the modem to answer. If the phone rings when you are not in terminal mode, you will neither hear nor see any indication that a call is coming in. If ATS= anything except 0, the Auto-Answer feature will be activated after the number of rings you specify.
