Both Rockwell and 90 k56flex modem Robotics the first producers of 56k modems requested the FCC allow their modems to transmit at a higher louder level allowing the 56Kbps speed. They were both turned down. Actual connection speed and throughput of any modem depends on the modulation of the signals, and the quality of that particular connection. The speed of your connection may vary from call to call. Two major factors effecting connection speed for a given modulation are:. Noise on the phone line you may not be able to hear.
Since most handsets were supplied by Western Electric and thus of a standard design, acoustic couplers were relatively easy to build.

An even lower-cost option was the Pennywhistle modemdesigned to be built using parts from electronics scrap and surplus stores. Like the A, it used different frequency bands for transmit and receive. 90 k56flex modem
It was similar in design, but used the lower frequency set for transmission. According to Vadic, the change in frequency assignments made the intentionally incompatible with acoustic coupling, thereby locking out many potential modem manufacturers.

This opened the door to direct-connect 90 k56flex modem that plugged directly into the phone line rather than via a handset. However, the cost of passing the tests was considerable, and acoustically coupled modems remained common into the early s.
The rapidly falling prices of electronics in the late s led to an increasing number of direct-connect models around In spite of being directly connected, these modems were generally operated like their earlier acoustic versions — dialing and other phone-control operations were completed by hand, using an attached handset. A small number of modems added the ability to automatically answer incoming calls, or automatically place an outgoing call to a single number, but even these limited features were relatively rare or limited to special models in a lineup. When more flexible solutions were needed, third party " dialers " were used to automate calling, normally using a separate serial port to communicate with the dialer, which would then control the modem through a private electrical connection.

The introduction of microcomputer systems with internal expansion slots 90 k56flex modem the first software-controllable modems common. This led to a series of popular modems for the S bus and Apple II computers that could directly dial the phone, answer incoming calls, and hang up the phone, the basic requirements of a bulletin board system BBS.
The seminal CBBS was created on an S machine with a Hayes internal modem, and a number of similar systems followed. The next major advance in modems was the Hayes Smartmodemintroduced in This allowed both data and commands to be sent 90 k56flex modem a single serial port. The rest fall in between, with the second fastest, GridNet, providing just half the speed of Compuserve.
