Atlanta-based Hayes Microcomputer Products Inc is scraping the bottom of the barrel to get the last ounce of benefit from its control of the Hayes modem command set: last week it announced the Hayes ‘302 Escape Sequence Patent Certification Programme and the availability of the Hayes ‘302 Escape Sequence Patent Icon to licensees of the Hayes ‘302 Patent; the Icon will identify licensed products containing the Hayes patented Improved Escape Sequence with Guard Time technology; the escape sequence consists of a pause, three plus signs and another pause, and is used to tell the modem to pay attention to the user’s commands – usually a command to hang-up the line; nonetheless, Hayes president Dennis Hayes, managed to keep a straight face while stating that ‘customers who have a concern for reliable transmission will look to the Hayes ‘302 Escape Sequence Patent Icon as a definitive symbol of reliable operation’; the usefulness of the programme is very limited Hayes says that certification covers implementation of the Hayes ‘302 Escape Sequence only and is not a test of Hayes compatibility or the implementation of the Standard AT Command Set.
