Wireless modems can be embedded inside a laptop or appliance, or be external to it. Modems grew out of the need to connect teleprinters over ordinary phone lines instead of the more expensive leased lines which had aclihk been used for current loop —based teleprinters and automated telegraphs.
Flaming or offending other users. Basically, the transmit output of one computer was wired aclihk the receive input of the other; this was true for both computers.
The next major advance in modems was the Hayes Smartmodemintroduced in The now-standard Hayes command set included instructions for picking up and hanging up the phone, dialing numbers, calink answering calls, among others. Some carriers implement flat rate plans for unlimited data transfers.

Even with improvements to the mkdem system allowing higher speeds, this splitting of available phone signal bandwidth still imposed a half-speed limit on modems. This provided a growing market for other vendors, who licensed the Hayes patents and competed on price or by adding features. Wireless modems are often referred to as transparent or smart. These values are maximum values, avlink actual values may be slower under certain conditions for example, noisy phone lines.
