Abstract

Computer apparatus including a modular modem device having communications indicators and an on/off switch provided in its front panel and an external configuration suitable for insertion into a slot provided in the front or side wall of a computer housing. Communications jacks, I/O connectors and power leads are provided at the rear thereof for connection to corresponding terminals of the computer. The on/off switch controls a tri-stateable switching device which captures a serial I/O port of the computer when the modem is in use but releases the port when the modem is not in use.

Claims

1. In a computer device having communications capability, the improvements comprising:

a computer housing including means provided in a wall thereof readily accessible and visible to a user for mounting a modem device;

a modem device affixed to said housing and having indicator means and on/off switch means accessible through said wall;

said modem device further including means forming an auxiliary serial port and switch means responsive to said on/off switch and operative to connect said modem device to said I/O port when said on/off, switch is in the on position, and to connect said auxiliary serial port to said I/O port when said on/off switch is in the off position;

means for connecting said modem device to external communications lines;

means for connection of said modem device to an I/O port of the computer device; and

means for coupling said modem drive to a suitable source of power.

2. In a computer device as recited in claim 1 wherein said computer housing is provided with a front slot specially configured to receive said modem device, the front panel of said modem device being substantially flush with the front panel of said computer housing.

3. In a computer device as recited in claim 1 and further comprising means for enabling said modem device to be combined with an additional peripheral device and inserted into an existing peripheral slot provided in said computer housing.

4. In a computer device as recited in claim 3 and further comprising means for enabling said modem device to be combined with an additional peripheral device and inserted into an existing peripheral slot provided in said computer housing.

5. Modem apparatus for insertion into a slot formed in the front of a computer housing comprising:

electronic modem circuitry;

means for providing power to said modem circuitry;

a front panel having an on/off switch;

at least one jack for connecting said modem circuitry to an external communications line;

means forming an auxiliary I/O port;

means for connection of said modem circuitry to a computer I/O port; and

switching means responsive to said on/off switch for connecting said modem to said computer I/O port when said on/off switch is in the on position and for connecting said auxiliary I/O port to said computer I/O port when said on/off switch is in the off position.

6. Modem apparatus as recited in claim 5 wherein said switching means is a tri-stateable switching device.

7. Modem apparatus as recited in claim 5 and further comprising indicator means disposed in said front panel for indicating communications activity when said modem circuitry is in use.

8. Modem apparatus as recited in claim 5 and further comprising supporting framework means for additionally supporting a peripheral device and adapted to enable said modem apparatus and said peripheral device to be mounted in a conventional disk drive slot.
