external modem and minicom

external modem and minicom

[pawel_l]

Hi:
wvdialconf found my modem attached to ttyS1:

[Dialer Defaults]
Modem = /dev/ttyS1
Baud = 115200
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 S11=55 +FCLASS=0
; Phone = <Target Phone Number>
; Username = <Your Login Name>
; Password = <Your Password>

but I couldn't activate it using minicom even I set it up to work with 
modem on ttyS1. Any suggestions, please?

Thanks,
Pawel.

Is it me or is this modem stuff very complicated.  I've tried over fifteen
command lines that are suppose to do the same thing but nothing happens.
I'm going to work on it again in the morning.

ordinaryily it's quite easy when
a) You know what you're doing
and
b) You know what you're working with.

In your case, actually identifying your modem and finding where Linux thinks 
it is is a problem. Probably if I had it here it would take me a few minutes 
to an hour.

Pavel just hasn't provided enough info to work on.

I like to see transcripts (by cut and paste) of what's on the screen, model 
numbers on devices and such. If I was working at your location I would insist 
on seeing the screen for myself.

What Pavel said is akin to, "My car won't start." I could make some guesses 
about the car if I knew what noises it made. I can't make any guesses at all 
about his modem problem with what information he offered.

Hi John and all:
This is US-Robotics 56k external fax/modem connected to ttyS1. 
There is no problem to run wvdial but I can't get any respons from 
minicom, even pressing typical combinations of keystroke gives me 
no respons, for instance, ctrl+z dos nothing, i can't close the program  
and need to kill minicom from another console. Besides, modem accepts 
dial-ins but it is another issue.

I have here an external modem attached to  ttyS0. One of the good things about 
external modems (at least, the ones I've seen) is for our purposes they're 
all the same.

I've typed the command
minicom -s
I have a menu. I choose Serial port setup using down arrow, press enter.
I see this:
    ┌─────────────────────────────────────────────────────
    │ A -    Serial Device      : /dev/ttyS0                                
    │ B - Lockfile Location     : /var/lock                                 
    │ C -   Callin Program      :                                           
    │ D -  Callout Program      :                                           
    │ E -    Bps/Par/Bits       : 38400 8N1                                 
    │ F - Hardware Flow Control : Yes                                       
    │ G - Software Flow Control : No                                        
    │                                                                       

I've trimmed the right hand side off in case it wraps when I send it.
Those values will do for me. You will want to choose A and change the name of 
the serial device.

I press Enter and return to the first menu. I choose Modem and dialing.
There's a lot of gibberish there which I will ignore. Items A through H you 
would need to check with your modem's manuals before you make changes. These 
are probably fine.

I press Enter to return to the previous menu.
I choose "Save as" and save it as "test."
Minicom says, "Configuration saved," leaves the message on-screen for a couple 
of seconds and returns to its initial menu.
I choose Exit ( NOT Exit from Minicom).
 
Minicom flashes a message, "initializing modem" for a couple of seconds.
Now the top of my screen (terminal window) looks like this:
Welcome to minicom 1.83.1

OPTIONS: History Buffer, F-key Macros, Search History Buffer, I18n
Compiled on Aug 28 2001, 15:09:33.

Press CTRL-A Z for help on special keys


OK

with the cursor just below "OK," and at the bottom of the screen,
 CTRL-A Z for help | 38400 8N1 | NOR | Minicom 1.83.1 | VT102 |      Offline

If I type commands at my modem, it talks back:
ATI
TP560 Data/Fax/Voice 56K Modem
OK

Let's make a phone call. As far as I know, nobody's home:
ATDT92503951
CONNECT
ÿ.@1593 0529 8 16      lH..
OK

Looks like the computer answered. We're not interested in what it has to say, 
trust me. Besides, "OK" is from the modem and it's hung up!
At the bottom of the screen:
 CTRL-A Z for help | 38400 8N1 | NOR | Minicom 1.83.1 | VT102 | Online 00:01

To leave Minicom:
Control-A X
A menu pops up, I press Enter.

If someone wants to publish this as a quick tutorial on Minicom that's fine by 
me.

Hi:
All of your commands worked for me but what I couldn't execute were the Minicom shortcuts menus such as ctrl+z or ctrl+x etc..

Thanks,
Pawel.

CPUS

[ADFM]

Excuse for being off topic. I have a 3 year old IBM ThinkPad which needs a new screen. The ThinkPad is a Pentium 2 333MHz. I am told that the price of replaceing, (about 2000 Canadian Dollars), the screen, I could just buy a new laptop. I am getting confused about the benefits between a 1+ GHz Pentium 3 and a Pentium 4. Can someone please tell me the benefits? What is a Xeon CPU? I like to keep the computer around for many years and use the laptop as a access technology demo machine after doing my own work.

access technology demo machine after doing my own work.

First point to make is that any new machine will be immensely more powerful 
than what you've had till now.

Pentium IV laptops are new, and as I understand it guzzle electrons like you 
wouldn't believe. If battery-charge life is important, I suggest you don't 
get one.

XEON processors are up-market versions of the Intel CPUs. I don't know the 
technical detail, but they're usually installed in serious servers. I would 
not expect to find one in a laptop.

I don't see the choice of CPU as being all that important. More important are 
disk size (and speed) and the amount of RAM. And ease of installing and using 
your accessibility technology devices.

I would guess that if you satisfy those requirements you will find yourself 
with a Pentium III because the economy computers are more likely to have 
economy CPUs, but don't shy away from Celerons if the computer meets your 
other requirements.
