Can anyone offer a suggestion on ways to connect two 300baud modems that do not have an answer switch so that a carrier can be generated on one end? Is it at all possible to emulate a carrier in software or is this reaching? Please email or post any realistic solution to this problem. These modems, if able, will be used to call a friend with an SE. My machine is also an SE. Modems we have are ComData Model #305E2-12 which have a voice data switch on the front panel.

Answer end: Connect your modem to the phone line. Put the switch on the front to data. It ought to answer the when the phone rings. Thus generating carrier. Do you have a manual for modem? Ted G.

If they are "Hayes compatible" and have the full command set, you can make one into an "answer" modem with the command ATD (phone #)R After dialing the number, the modem goes into answer mode. It's for calling modems that are "originate only." If the modems are directly connected, use "ATDR" on one, and "ATD" on the other. Note that this only works at 300 baud ... -- Ed Nather Astronomy Dept, U of Texas @ Austin {allegra,ihnp4}!{noao,ut-sally}!utastro!nather nather@astro.AS.UTEXAS.EDU

If there is no answer switch, then no, you can't connect the modems, unless of course you open up one of them and muck around with the frequencies.

We work with this problem EVERY DAY. It's really quite simple. On ome machine you type (caps) "ATA" on the other machine type (caps) "ATO" Of course, this assumes Hayes compatability. We use this to input/put news stories TRS80 laptops<->Macs. It works well and no sweat, no null modem, etc. Hafa Adai from Saipan, Mariana Islands Y'all.
