I CANNOT get any response to my dialout command (ATDT13174446354 & cr)
You really need an AT command set, and to read the thing end to end! In
the old days, modems came with a proper manual (on dead tree) that explained
all this in gruesome detail.
Have you accidentally stored settings that will turn off some of the
responses? You used to be able to adjust the level of reporting from the
modem. From my old modem manual ...
ATQ0 Result messages turned on <- You probably want this
ATQ1 Result messages turned off
ATV0 Result codes as numeric
ATV1 Result codes as words <- You probably want this
ATX0 Result codes: Basic. Dialling is blind, regardless of dial tone.
"CONNECT" will be returned on getting a remote modem.
ATX1 Result codes: Extended. Modem now indicates connection speed in CONNECT
response, e.g. "CONNECT 1200" (haha! How quaint ...)
ATX2 As X1, but with dial tone detect
ATX3 As X1, but with busy tone detect
ATX4 As X1, but with busy AND dial detect <- Hello, this looks good!
Modem codes (not exhaustive, but the ones you'd need)
0 OK
1 CONNECT (you won't see this for voice use?)
2 RING (incoming)
6 NO DIAL TONE
7 BUSY
8 NO ANSWER
33 FAX
Newer modems can, I think, detect "VOICE" as a response, but I don't
know how they manage it. "It's sound, it's not a modem, it's not a fax,
it's not call progress tones or DTMF, therefore voice?"
problems whatsoever, but I don't get any AT response......(like RING,
RING is in response to incoming calls. It keeps saying "RING" whenever
the modem detects an incoming ring.
These are "connection progress" messages I should be getting from the
originating modem to it's PC and after all. like I say, I get an OK on
any other good command.
Try ATQ0 ATV1 ATX4 and see what happens. Maybe you'll get more responses back?
Does this particular Hayes like modem have options to
cause it to dump it's command set and full blown status report?
I used to find those very enlightening as far as options go.
Which company's Hayes clone is this, by the way?

The Basic Hayes Command Set
In alphabetical order:
Table B.1. Basic Hayes Command Set
Command Description Comments

A/ Repeat last command Don't preface with AT. Enter usually aborts.
B0 or B Call negotiation V32 Mode/CCITT Answer Seq.
B1 Call negotiation Bell 212A Answer Seq.
B2 Call negotiation Verbose/Quiet On Answer
D Dial Dial the following number and then handshake in originate mode.

;
Remain in command mode after dialing.
!
Flash switch-hook (Hang up for a half second, as in transferring a
call.
L
Dial last number
E0 or E No Echo Will not echo commands to the computer
E1 Echo Will echo commands to the computer (so one can see what one
types)
H0 Hook Status On hook - Hang up
H1 Hook status Off hook - phone picked up
I0 or I Inquiry, Information, or Interrogation This command is very
model specific. I0 usually returns a number or code, while higher
numbers often provide much more useful information.
L0 or L Speaker Loudness. Modems with volume control knobs will not
have these options. Off or low volume
L1 Low Volume
L2 Medium Volume
L3 Loud or High Volume
M0 or M Speaker off M3 is also common, but different on many brands
M1 Speaker on until remote carrier detected (i.e. until the other
modem is heard)
M2 Speaker is always on (data sounds are heard after CONNECT)
N0 or N Handshake Speed Handshake only at speed in S37
N1 Handshake at highest speed larger than S37
O0 or O Return Online See also X1 as dial tone detection may be
active.
O1 Return Online after an equalizer retrain sequence
Q0 or Q1 Quiet Mode Off - Displays result codes, user sees command
responses (e.g. OK)
Q1 Quiet Mode On - Result codes are suppressed, user does not see
responses.
Sn? Query the contents of S-register n
Sn=r Store Store the value of r in S-register n
V0 or V Verbose Numeric result codes
V1 English result codes (e.g. CONNECT, BUSY, NO CARRIER etc.)
X0 or X Smartmodem Hayes Smartmodem 300 compatible result codes
X1 Usually adds connection speed to basic result codes (e.g. CONNECT
1200
X2 Usually adds dial tone detection (preventing blind dial, and
sometimes preventing AT0)
X3 Usually adds busy signal detection
X4 Usually adds both busy signal and dial tone detection
Z0 or Z Reset Reset modem to stored configuration. Use Z0, Z1 etc. for
multiple profiles. This is the same as &F for factory default on
modems without NVRAM (non voltaile memory)
