I have connected a gsm/gprs modem to the putty terminal on windows 7 for serial communication. The AT commands work but the response from the modem is displayed as special characters which is not readable. Both the port and the modem is configured at 9600 baud. I changed the character encoding to utf-8 (Window->translation->character set) but the results were the same. Please help.

The character encoding of strings sent to/from the modem is controlled with the AT+CSCS command, Select TE character set. If you want UTF-8 run AT+CSCS="UTF-8". You can check current selected character set with AT+CSCS? and supported sets with AT+CSCS=?. See the 27.007 specification for more details.
