ITEM 1. Security and Issuer

This Schedule 13D on the Common Stock of General DataComm Industries, Inc. (the “Issuer”) is being filed on behalf of the undersigned Reporting Person (the “Schedule 13D”).

ITEM 2. Identity and Background

This statement is being filed by Howard S. Modlin (the “Reporting Person).

The foregoing person owns beneficially more than 5% of a class of equity securities of the Issuer.

Howard S. Modlin has an office at 445 Park Avenue, 15^th Floor, New York, NY 10022, and is Chairman of the Board, President, Chief Executive Officer and Secretary of the Issuer and has been an officer and director of the Issuer for the past five years. He is an attorney and President of Weisman Celler Spett & Modlin, P.C., a law firm, for the past five years.

The Reporting Person is a citizen of the United States.

During the past five years the Reporting Person has not been (a) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceedings was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, Federal or State securities laws or finding any violations with respect to such laws.

ITEM 3. Source and Amount of Funds or Other Consideration. The Reporting Person received a Stock Option to acquire 551,121 shares of the Issuer’s Common Stock at 20 cents per share. The Stock Option is exercisable in five equal annual installments commencing October 10, 2007 and expires ten years from issuance on October 9, 2016.

ITEM 4. Purpose of Transaction. The purpose of the acquisition of the securities was to receive a Stock Option under the Issuer’s 2005 Stock and Bonus Plan. The transaction was unanimously approved by the Issuer’s Stock Option Committee of the Board of Directors. The Reporting Person has no current plans which relate to or would result in:

(a) The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer other than stock option grants under the Issuer’s stock option plans;

(b) An extraordinary corporation transaction, such as a merger, reorganization or liquidation, involving the Issuer or any of its subsidiaries;

(d) Any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board;

(e) Any material change in the present capitalization or dividend policy of the Issuer;

(f) Any other material change in the Issuer’s business or corporate structure;

(h) Causing a class of securities of the Issuer to be deleted from a national securities exchange;

(i) A class of equity securities of the Issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934; or

(j) Any action similar to any of those enumerated above; but the foregoing responses above do not apply to any such actions of the Issuer in the ordinary course of business which may result from actions taken by the Reporting Person as an executive officer or a director of the Issuer or its subsidiaries.

ITEM 5. Interest In Securities Of The Issuer

(a) The Class B Stock of the Issuer is convertible into the Issuer’s Common Stock on a share for share basis. The aggregate number and percentage of securities to which this Schedule 13D relates is 4,445,402 shares of Common Stock and Class B Stock, representing 54.89% of 8,098,443 shares of Common Stock and Class B Stock of the Issuer. This number of shares outstanding is arrived at by taking the number of shares reported as being outstanding in the Issuer’s Form 10-QSB for the quarter ended June 30, 2006 disclosing 3,468,090 shares of the Issuer’s Common Stock outstanding, 653,947 shares of Class B outstanding or an aggregate of 4,122,037 shares of the Issuer’s Common Stock and Class B Stock outstanding and adding thereto 1,050 shares if the Reporting Person were to exercise two out-of-the-money director stock options held by him described below plus 909,090 shares issuable on exercise of the warrant issued April 20, 2006, 2,084,204 shares issuable on exercise of the warrant issued December 9, 2005, 761,614 shares acquirable on exercise of the five year warrant issued on September 30, 2004, 110,224 shares of the 551,121 shares acquirable in the next 60 days on exercise of a Stock Option issued January 26, 2005, and 110,224 shares of the 551,121 shares acquirable in the next 60 days on exercise of a Stock Option granted November 22, 2005; the balance of the shares acquirable under both such options are not included in the calculation because they cannot be acquired in the next 60 days and only vest in 20% increments annually on the anniversary of grant.

The Reporting Person is deemed to beneficially own the Common Stock as follows:

Name		Shares of Common Stock Deemed Owned*			% of Common Stock Outstanding			Shares of Common Stock if Converted from Class B Stock*			Total Shares of Common Stock Deemed Held*			% of Shares of Common Stock Outstanding as Adjusted
Howard S. Modlin			3,985,459			53.54			459,943			4,445,402			54.89

9,053 of these shares are owned by the Reporting Person’s law firm. Pursuant to Rule 13d-3 an additional 909,090 shares are deemed owned on exercise of the warrant issued April 20, 2006, 2,084,204 shares are deemed owned on exercise of seven year warrant issued December 9, 2005, 761,614 shares are deemed owned on exercise of a five year warrant issued September 30, 2004, 1,050 shares are deemed owned based on options to purchase Common Stock which could be exercised by the Reporting Person as follows: 450 at $37.50 per share and 600 at $26.875 per share, respectively, expiring March 4, 2008 and October 20, 2009 respectively, 110,224 shares at 61 cents per share are deemed owned pursuant to an option for 551,121 shares expiring on January 25, 2015 and 110,224 shares at 50 cents a share under an option granted November 22, 2005. The total does not include an aggregate of 99,722 shares of Common Stock or 2.92% of the outstanding shares consisting of (i) 11,200 shares of Common Stock and 3,400 shares of Class B Stock owned by the Reporting Person’s wife, the beneficial ownership of which the Reporting Person disclaims, and (ii) an aggregate of 85,122 shares held as trustee for the benefit of two children of Charles P. Johnson, the Issuer’s former Chairman, of which the Reporting Person is the sole trustee, the beneficial ownership of which the Reporting Person disclaims. Such shares held as trustee consist of 78,683 shares of Class B Stock convertible into a like number of shares of Common Stock, 4,607 shares of Common Stock and an additional 1,832 shares of Common Stock if 20,000 shares of the Issuer’s 9% Cumulative Convertible Exchangeable Preferred Stock are converted into Common Stock at $136.50 per share. In calculating the aforesaid percentage of excluded shares, the amount of 1,832 shares acquirable on conversion is added to the shares of the Issuer outstanding at June 30, 2006. The 53.54% deemed owned is obtained by dividing the number of Common Stock shares deemed owned by the outstanding Common Stock increased by adding all shares acquirable on exercise or conversion in the next 60 days. The balance of the shares under both the option expiring January 25, 2015 and the Stock Option issued November 22, 2005 and shares issuable under the option granted October 10, 2006 are not included because no such shares may be acquired in the next 60 days.

(b) The Reporting Person has the sole power to vote or direct the vote, and sole power to dispose or to direct the disposition, of the shares of the Issuer reported for him for his own benefit, as well as to direct the vote and dispose of the shares held by him as trustee.

(c) Information with respect to all transactions in the shares of the Issuer which were effected during the past sixty days by the Reporting Person is set forth on Schedule I annexed hereto and incorporated herein by reference.

(d) Not applicable.

(e) Not applicable.

ITEM 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. None except the four outstanding options previously granted by the Issuer reported in Item 5, the Amended and Restated Notes issued December 9, 2005, the Amended and Restated Note issued April 20, 2006, the three previous Warrants issued to the Reporting Person, an Additional Senior Security Agreement, as amended securing all Amended and Restated Notes and the new Stock Option Agreement. The Reporting Person disclaims any interest in the Amended and Restated Notes issued to John L. Segall who has also previously loaned an aggregate of $550,000 to the Issuer and whose Amended and Restated Notes are secured by such Additional Senior Security Agreement. The undersigned and Mr. Segall have no agreements whatsoever with respect to any securities of the Issuer except for the fact all Amended and Restated Notes are secured by the same Additional Senior Security Agreement.
