You want to use pcAnywhere to connect to a host by using a cellular phone attached to a modem by an adapter cable.
In a normal dialing situation, the Windows TAPI (Telephony Application Programming Interface) initializes the modem using command strings located in the modem's .INF file. These commands include instructions to dial the destination phone number. The modem then dials the number and establishes a connection to the destination modem.
When using a cell phone attached to a modem, it is the cell phone that is initialized and instructed to dial rather than the modem. This requires a means to pass AT (modem) commands directly to the cell phone. You can accomplish this by using an adapter cable and by reconfiguring the modem properties for your connection. This action is not supported with pcAnywhere and is not guaranteed to provided reliable service.
The adapter cable plugs into the cell phone at one end and the modem at the other. It creates the channel for AT commands to pass from the modem to the cell phone. Those commands must be entered manually (TAPI will not do it). To do this, reconfigure the modem properties to launch a terminal window prior to connection. With this configuration, TAPI will not issue any modem commands; rather, you will enter them manually and the adapter will send them to the cell phone.
To configure pcAnywhere to work with a cellular modem
- Open pcAnywhere.
- Right-click the remote connection item selected for this connection.
- Select Properties, and then click Details.
- Select the Options tab.
- Select Bring up terminal window before dialing, and then click OK.
- Click OK again to close properties.
Start the connection. A black terminal screen appears in a gray window. Type in the commands for the cellular modem here (these will come from the cell phone manufacturer). Press the F7 key when done entering information. The cell phone should dial at this point and make the connection.
- A digital cell phone using a digital modem can only connect to a digital (ISDN) device at the host end. The modem rule of digital to digital, analog to analog applies.
- Do not expect to make connections at speeds faster than 4800 bps. This speed is too slow to display the user interface from the host, so connections are really only effective for file transfers.
- If the cell phone moves into a new cell there may be a "click" on the line. The host modem may interpret the click as the remote end dropping the connection and can subsequently close the connection at the host end.
