Click the "Port Settings" icon and configure the settings as follows: Baud Rate = 19200 Parity = None Stop Bits = 1 Data Bits = 8 Duplex = Full Software Flow Control (Xon/Xoff) = Off 4. For ZMODEM transfers, configure the settings as follows: Transmit Method = 4K-Window Error Detection = 32-bit CRC 5. Configure other settings as follows: Flow Control = Hardware Fax Class = Class 2 Maximum Transmit Rate = 9600 Maximum Receive Rate = 9600 c. Save your settings. 61 iM1000-Data Modem TROUBLESHOOTING If you have a problem while setting up and using your modem for data calls, read the symptoms and troubleshooting tips provided in the following table. If the system responds with an error message, refer to "Error Messages" on page 64. Note that the response time for a wireless data call is slower than that for a wireline (normal) data call. Table 3: Identifying Symptoms Symptom Your modem does not respond to AT commands. Troubleshooting Tips Make sure that: · The modem is powered on. · The cable is connected to the correct port and that this is the same port specified for use in your communication software. · The modem is set to the same baud rate as that specified in your communication software. Make sure that the baud rate setting in your software matches the baud rate setting on the modem. Make sure that the S0 register contains a value other than 0 (zero) by issuing an AT&V command. You can also explicitly set ATS0=x from the software's command mode where x is any number between 1 and 255. Make sure that the S7 register contains a value greater than or equal to 60 by issuing an AT&V command or by explicitly setting ATS7=x where x is any number between 1 and 255. Computer screen appears distorted. No characters are displayed on the computer screen. The modem does not auto-answer incoming data calls (not default operation). The NO CARRIER message display when the modem attempts data calls. 62 Troubleshooting Table 3: Identifying Symptoms Symptom Received data is unrecognizable. Troubleshooting Tips Make sure that flow control is set to RTS/ CTS (that is, hardware flow control is enabled) in the communication software and set to &K3. Make sure that flow control is set to RTS/ CTS (that is, hardware flow control is enabled) in the communication software and set to &K3. Make sure that: · Drop DTR on Hang-Up is enabled in the communication software. Check the signal strength icon to be sure the signal is not weak. Data is intermittently lost. The modem does not respond to a hang-up command from the software's command mode. Modem seems to respond slowly than usual and/or drops connections occasionally. Software reports various modem initialization errors when it attempts fax calls. Make sure that: · The modem is switched on. · The cable is connected to the correct port and that this is the same port specified for use in your communication software. · You are subscribed to the Data feature with your iDEN carrier. · The baud setting on the modem matches the baud setting in your software. [. . . ] The Clear to Send signal passed from the local modem to the local terminal when the data port is ready to transmit data. When your modem is in this mode, it is waiting to receive AT commands that you type from your communication software.
