[comp.sys.apple] Simple Hayes modem help needed

ART100@PSUVM.BITNET ("Andy Tefft 862-6728", 814) (01/11/89)

I'm using a Hayes Smartmodem 1200 right now. I traded it for a while with
a friend who couldn't get it to work on his PS/2 (it said 'no DSR' and
my modem worked fine, so I'm letting him use it. It's a dumb modem so
nothing hayes really applies to IT) I'm having some small problems with
the Hayes though:

1) a minor annoyance is a relatively loud 60 Hz hum coming out of the speaker.
Anyone know what causes this one? It's not affecting performance.

2) My friend doesn't have a manual for the Hayes, just a brief list of
switch settings. I don't get any output from the modem, no matter what
I do, as far as replies like 'on line' and echoing of my commands. I tried
setting the switch he has listed as 'echo commands on screen' but this
makes no difference. One switch (switch 4) causes both the SD and RD lights
to light up when I type commands but it still doesn't show up on the screen
(the commands work though, in either position).

my current switch settings (switches 1-7 accessible removing the front panel):

up down down up up up up down

(it's not marked which is on and which is off)


Can anyone give me quick settings which will make this work right with
my //c? It works ok not but not RIGHT.

Please mail replies directly to me if possible.

Andy

Try turning down the volume (the volume control is next to the phone jack
connector on the back).

You're in luck.  Before a zillion inexpensive clones that work just as well
as the Hayes Smartmodem were advertised in every mail order catalog, I
spent (what today is) an embarrassing amount of money on a real Smartmodem,
AND I have the manual right here...

You want switch 2 UP and switch 3 DOWN to get the modem to respond to commands
with an English word.

Up and down each have a meaning on most of the switches, so "on" and "off"
wouldn't really make sense for some of them.

I recommend the factory settings for use with just about every flavor of
Apple 2 and Apple 2 commware (SOFTERM can make use of carrier detect
- switch 6 - but it doesn't have to be set that way, and I prefer the
factory settings even with SOFTERM).

I just popped the front off my Smartmodem to make sure I AM in fact using
all of the factory settings with my //c (I am).

down up down up down down up down

Switch                     Function
  1              DTR (pin 20), down = true
  2              results code, up = English, down = number if switch 3 is down
  3              echo results code, down = yes
  4              echo characters while in command state, up = yes
  5              auto answer incoming calls, up = yes
  6              CD (carrier detect), down = true
  7              phone jack, up=RJ11 (modular jack) down=RJ12,RJ13 (multiline)
  8              recognize "AT" command, down=yes

Switches 2,3,4, and 5 can be changed by software (AT commands), the others
can't be altered by software.
