I’m not saying that it is echoing. if i type any command in the Hyper Terminal it is showing some ASCII characters. I don’t know whether it is a ASCII/ Unicode that is what i mentioned in my Previous post.
So please give me a suggestion to make it work asap.
I’m having one more problem with some other Modem.
I’m Using a WAVECOM WMOD2
I’m using Hyper terminal to connect the Modem, iI set the Modem at Mexico with Telcel carrier. And i set the port settings as Bits Per Sec : 9600
Data Bits : 8
Stop Bits: 1
Flow Control: None
Moreover i connected the modem with a USB to my PC via a USB-Serial convertor, because i don’t have the serial port.
the output of the modem is shown below. [size=150]Using USB- Serial Convertor[/size]
This is the output when i connected directly to a serial port of some other system with same port settings.
[size=150]Not using Usb - serial Convertor.[/size]
If i gave any command more than once it is responding. I don’t know why.
The so-called “Baud Rate” is the speed at which a serial port works; that is, the speed at which it sends and receives data.
For two serial ports to communicate, they must both be set to the same Baud Rate - in this case, the serial ports are on the modem, and the the PC’s COM port.
You set the modem’s Baud Rate with the AT+IPR command - it is entirely independent of the GSM carrier.
Obviously, sending the AT+IPR command requires that you have the PC and Modem serial ports already set to the same Baud Rate. If you don’t know what Baud Rate the modem is set to (and it is not in “Auto-Baud” mode), you will just have to find it by trial-and-error…
I’m using M1306B Modem. I just connect that with the use of Hyper Terminal & using a USB - Serial Port Converter.
If i type any thing I’m getting the junk characters in the screen. For this i Got two solutions
Problem with the port settings
Problem with the Cable
Let me know these are the only problems or some other things to be consider.
Do you think you could go easy on all the colour, etc?
Port settings are by far the most likely cause of this; until you can state with 101% certainty that you have the port settings correct - on both the modem and the PC - there is little point worrying about anything else!
Is your service somehow “locked” to a particular mobile?
As already explained, communication is possible only when both the modem and the terminal have the same settings - if you change the terminal without also cahnging the modem to match, then, of course, they will no longer communicate!
