My User Port RS-232 interface has a switch that can be set to either Hayes or 1670. I have never really understood why. I thought that an RS-232 interface just converts between RS-232 voltage levels and User Port RS-232 voltage levels. I use the RS-232 interface for transferring files between my C128 and my PC using a null-modem cable. I have set the switch to Hayes and that works well. I'm sorry if something like this has already been discussed in this email thread. I must admit that I haven't had time to read all of the emails so I don't know what the original problem was. /Christian Johansson ----- Original Message ----- From: "Mike Paull" <email@example.com> To: <firstname.lastname@example.org> Sent: Saturday, February 14, 2004 6:20 AM Subject: RE: Commodore Modems - C1660 and C1670 > Hi William, > > Perhaps they are not strictly hayes commands, maybe they are just additional > commands that another company added along the way and were adopted by some > manufacturers and either Commodore didn't or the 1670 was produced prior. > > Mike > > > > -----Original Message----- > > From: email@example.com > > [mailto:firstname.lastname@example.org]On Behalf Of William Levak > > Sent: Wednesday, 11 February 2004 2:30 PM > > To: email@example.com > > Subject: RE: Commodore Modems - C1660 and C1670 > > > > > > On Tue, 10 Feb 2004, Mike Paull wrote: > > > > > <SNIP> > > > > > > As well as what is mentioned below there is also an AT command > > that allows > > > you to set DCD true all the time rather than actually check the > > line.
