[. . . ] To change the speed at which your modem connects after dialling: · Place front panel Option switches 5 and 6 in the On (or Left) position to select Dumb mode · Press the Mode button until the correct speed is indicated on the front panel Mode LEDs Refer to the table printed in your modem Installation Guide -- it shows the meaning of each combination of the Mode LEDs. To change the speed at which your modem connects after answering an incoming call: · Place front panel Option switch 6 in the Off (or Right) position to select Smart mode · Connect your modem to a personal computer -- refer to the modem Installation Guide for details · Run a communications program (such as Cooee or MicroPhone) and enter "local mode" or "terminal mode" · Type: ATBx&W <E> where "x" is a valid setting of the B command. For example, ATB13&W selects V. 32 (9600 bps) mode. The B command is used to set the communications standard used by your modem. Refer to the Command Card, supplied with your modem, for a description of the B command. 6 Dumb-Mode Guide Hints for Unix Computers and Multiplexers Many Unix computers and multiplexers which offer synchronous communications ports cannot cope with the response messages generated by the modem. For this reason, you may wish to switch off response messages before you connect your modem to the Unix computer or multiplexer. · Place front panel Option switch 4 in the Up position to select Smart mode For ProRack modems, place switch 6 in the Off (or Left) position. · Connect your modem to a personal computer, a Unix computer or a serial server -- refer to the modem Installation Guide for details · Run a communications program (such as Cooee or MicroPhone for Windows, or TIP or CU for Unix) and enter "local mode" or "terminal mode" · Type: ATE0Q1&N0&W <E> · Exit the communications program This command switches off response messages and character echo, causes the modem to ignore characters sent to it from the host while dialling or answering, and saves the changes in the modem. If you are dialling from a synchronous multiplexer, or if you are using a "pseudo leaded line" application with SLIP, CSLIP or PPP, you must use stored number dialling. Refer to Synchronous Mode 2 in the Modem Reference Guide, which is available from Telesales. I Want More Information If you want more information about the AT commands supported by your modem, you may purchase the Modem Reference Guide. This book provides detailed information about the AT commands and S Registers supported by your modem, as well as information about how to use features such as synchronous mode, security and DES encryption. Dumb-Mode Guide 7 To purchase the Modem Reference Guide, call NetComm Telesales on (02) 888 5533. To assist with ordering please have the model name and number of your modem ready (these are found on the serial plate of your modem). Leased Line Operation Details of your modem's leased lines features are found in the Modem Reference Guide, available from Telesales or your dealer. 8 Dumb-Mode Guide Dialling in Dumb Mode There are three ways of dialling in dumb mode: t Use a telephone handset connected to the modem. t Store a telephone number in the modem and then have the computer raise the DTR signal. t Store a telephone number in the modem and then press the Talk/ Data switch. ProRack modems can dial only by raising the DTR signal to dial a stored telephone number. Dialling with a Telephone Handset Manual dialling requires a telephone handset be connected to the same phone line as your modem. Use a telephone cable with a "piggy-back" socket to connect your modem and telephone handset to the same phone line (refer to your Installation Guide for details). This form of dumb-mode dialling is not supported by ProRack modems. · Set up your modem in "smart mode", using the AT commands. · Place front panel Option switch 4 in the Down position (select Dumb mode) · Place front panel Option switch 6 in the Down position (select Originate mode) · Place front panel Option switch 3 in the Down position (disable auto-answering) Your modem cannot dial if auto-answer is enabled. · If necessary, use the Mode button to select the required communication speed The connection speed of the modem is indicated by the Mode LEDs. · Raise the DTR signal on your computer If your modem has a TR front panel LED, it glows when DTR is raised. · Press the Talk/Data button to Data The Talk/Data button must be changed from Talk to Data to cause the modem to dial. [. . . ] · Type: AT&W <E> The modem set up is saved. 14 Dumb-Mode Guide · Place front panel Option switch 4 in the Down position (select Dumb mode) For ProRack modems, place Option switch 6 in the On (or Left) position. · Place front panel Option switch 6 in the Up position (select Answer mode) For ProRack modems, place Option switch 8 in the Off (or Right) position. · Place front panel Option switch 3 in the Up position (allow autoanswering of incoming calls) For ProRack modems, place Option switch 5 in the Off (or Right) position. If the &D2 command has been issued to the modem, DTR must be raised by your computer. [. . . ]
