AT&T 4024C & Hayes 2400

[Dominick Samperi]

I just installed an AT&T 4024C modem for use with a 3B2/300, and it seems
to work fine, except for one problem: the 4024 modem must be called 2-3
times before it sends a carrier that my Hayes 2400 understands. Most of the
time when I call the 4024 with my Hayes modem I hear the 4024 answer,
and send what sounds like a carrier (to human ears), but the Hayes modem
does not recognize it. I had the same problem calling with other Hayes
modems. Any ideas?

It was not clear how the dip switches on the 4024 should be set, but I
set them for 2400 Async operation. Perhaps some kind 4024 user (on a
3b2) can send me his/her dip switch settings? Thanks in advance.

I tried things like making my 2400H gettydefs entry point to itself, but
this didn't help. Here is the Dialers entry that I'm using (but I
realize that this shouldn't effect dialins):

4024 =+-, "" \r\c :--: O4=n\r n--n O12=y\r y--y \T\r\c red
