Optimizing Modem Performance: Understanding Communication Parameters

Click For Summary
Communication parameters are crucial for modems as they define how data is transmitted over the connection. These parameters include settings like baud rate, control protocols, and IP encapsulation, which must match between the communicating modems for effective data exchange. Modems primarily operate at the physical and data link layers (Layer 1 and Layer 2) of the OSI model, while higher layers are managed by the connected computer. Proper configuration ensures compatibility and optimal performance during dial-up connections.

Why are communication parameters important when a computer uses a modem?

Thank you in advance

If you're talking about the string that you can pass to the modem when dialing, it sets certain preferences for operation, such as the modem's speaker volume and the like.
 
Well you have to tell the modem how to send data to the wire, I take it you are talking about an analoge modem (ISDN Dslam ATM all work differently)...

If you are dialing up to another modem for both modems to communicate they have to speak the same lanagauge, per say... For example the baud rate has to be the same, the control protocol has to be the same the IP encapsulation has to be the same.. Modems only really deal with layer 1 and layer 2 in networking speak layer 3 and above would be handled by your PC... I could go on but Id bore you

Thread 'ChatGPT Examples, Good and Bad'

I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...
