As you know, I've been an active participant in this work. I don't think there are any "alterior motives" involved, just serious and sincere technical disagreement with regard to whether or not this DTE-DCE protocol should be mandatory in all fax modems. But at the meeting of TR-29.2 earlier this month, the committee voted to make it optional. There are a few more relatively minor, but technically important, issues to be resolved (mostly having to do with handling of error conditions), and then Class 2 should be ready to go out for ballot again. I expect this to happen at the TR-29 meeting in August in Yountville, CA. -- Toby -- Toby Nixon, Principal Engineer | Voice +1-404-840-9200 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.
