the computer museum says..... Hayes Micromodem 100 --------------------------------------------------------------------------

---- Hayes pioneered the 'Smart Modems'. These modems fit inside the computer

could be programmed to automatically dial a phone number or answer the phone. Hayes advertised: "Since it is a direct connect device, it has none of the losses and distortions associated with acoustic couplers. There are two program selectable speeds for the Micromodem 100-- a high speed of 300 BPS (baud) and a factory set low speed of 110 BPS. The low speed may be hardware adjusted from 45 to 300 BPS at http://www.syssrc.com/html/museum/html/modem_hayes100.html ----- Original Message ----- From: "Vintage Computer Festival" <vcf(a)siconic.com> To: "Classic Computers Mailing List" <cctalk(a)classiccmp.org> Sent: Thursday, September 25, 2003 12:48 AM Subject: Re: *****hayes modem history..... > On Wed, 24 Sep 2003, ed sharpe wrote: > > > question: was the s100 board the first version of the Hayes micromodem > > with the at command set or was the standalone first?

Yes, back in "those days" a DAA was required for connection to the precious phone circuits... I had one of these modems when they were new (still have it, in fact - I never throw anything away, alas.) While trying to establish a second line for data connections, I was repeatedly asked "what kind of business are you running?" Ma Bell had difficulty understanding a "hobby" use for a modem. After *many* phone calls, I was eventually assigned a "data account representative" and received the work order number and target installation date for my provisioning. The day came and *three* guys showed up with several boxes of equipment. They installed the extra line, made measurements and recorded the line quality to the central office and left me with a packet of paperwork. The installation charge was $0 and the monthly charge was the normal residential rate (they got quite a few more $$ from the commercial customers, most likely explaining the extra effort expended on getting things "just right.") While in school, I moved several times over the next few years and each time several people came out and reconnected everything and went through the same line tests. This for the 'data' line only - the voice line got the usual 15 second "it seems to work" treatment. I think I still have my cancelled check with Dennis' or his partner's signature on it... They were a small company back then - having just escaped from his garage. Those were the days! -Gary Ed Sharpe wrote: > yes the s 100 part is that way also... the separate chingus is the

well in looking into the s100 board it seems to indicate that many many options could be set under program control, however I am still not sure it is the at command set...

maybe it was some binary sent to it.....

I just wish I checked remember how the micromodem on the apple worked I suspect the same as the s100 board...
