Hi all
Where can I find a step by step guide for serial port in oscada?
I read the demo documentation but I did not find anything useful.
I just want to communicate with a GSM modem.

Partialy you can this find into "QuickStart" and the manual's videoaddon (only Russian) for DAQ, and other things represented enought into "Transport.Serial" manual.

Hi Roman
I have read "QuickStart" 2 times by now. to the end of the 4th part. But Unfortunately the english is poor and I can not understand what does the author actually means...
I can create a serial port object but I dont know how to send some bytes via that object. I guess I need an another module which can generate some bytes for the serial object. I will be thankful if you can help me about that.

About transport "Serial" using from DAQ modules shortly described into part 4.1:
Other types transports created by like to "Sockets" method, but configuration typical different only at record format for address and timings. In case of transport module "Serial" into address field write the path to serial device, speed, and format. For converters USB->Serial that address you need learn into operation system, for example by console command "$ dmesg", just after the converter connection.

Some bytes ordinary sent: DAQ module, the user by tab "Request" or from user's script by user API function SYS.Transport.messIO()

Hi roman and thanks for the answer. See I have got this far (step by step)
1- sudo openscada_demo (sudo to have access to serial ports)
2- I open the Demo Station
3- Under Data Accquisition I select Module and then ModBUS and then choose KM101
4- I set the Transport Address Serial.testModem
5- Then I go to Transports and under serial interfaces and Output transport I select "Test Modem"
6- I set my device address in the Address field and do not change anything else
it will be in fact:
/dev/ttyUSB0:38400:8N1::0679859815
my device is a HUAWEI GSM Modem which I have communicated with it via serial port previously and is working. The only thing I want to do is to send two bytes "A" and "T" to this modem and recieve its response (which is "O" and "K" I think).
7- I check the "Running" checkbos for the "Test Modem" and the program crashes...
I will be thankful if u can tell me exactly what further step should I take in order to recieve the data bytes... and please tell me step by step... I can not figure what your docmuntations are all about (sorry)
attached I have put screen shots of my configurations
Thanks in advance

Why? You need configure permit to the serial devices.

On your screen shot you do not applied the address!
And why my telephone number left?

What OpenSCADA version used?
On OpenSCADA work version I have not any crash.
Send me crash report: http://wiki.oscada.org/HomePageEn/Doc/CrashReport

Path to serial device and Telephone number set correct for self.
Next establish the connection, by set "Running".
Next into appear tab "Request" http://wiki.oscada.org/HomePageEn/Doc/ProgrammManual/part4/files?get=subsys_tr_mod_tr_otr_req_en.png write and send your bytes.
And carefully read the documentation before next questions!
