[comp.dcom.modems] Hayes Personal Modem 2400 questions

carlton@aldebaran.uucp (Mike Carlton) (10/28/89)

Can anyone tell me how to shut off the autodisconnect "feature" on the
Hayes Personal Modem?  The modem automatically drops the connection after
10 minutes of no data transfer, I don't consider this a feature.

Unfortunately, the modem comes with no technical documentation, so I don't
know if this feature is programmable or not.  I'd settle for setting it
to 255 minutes or something like that.

Also, could someone email me the Hayes command set and a description of 
the standard registers?  

thanks in advance,

How about the modem control lines (DTR, DSR, CARDET) on the Hayes
Personal 2400?  There are no technical docs but a quick look with
a voltmeter shows CARDET always asserted and the modem doesn't
hang up when DTR(pin 20 on the DB25) is brought low.  Both of these 
behaviors were good reasons to use a Hayes 1200 as a dial-in/dial-out 
Unix modem.  Is there a way to enable intelligent use of these signals?

Thanks!  Please respond by e-mail if possible as I may not get 
around to here for a while.
