Dear Denis, did you see my solution? You can use ls to get the available ttyUSB devices attached and you can use ls to get the locks in the /var/lock folder.

Re: [Synalist] SYNASER - port initialization problem
One idea concerning to your problem: AFAIK, Synaser inits COM port by the sequence: - clear DCB - set some fields of DCB - SetCommState(DCB) Not anymore :) whereas typical implementation is - GetCommState(DBC) - change some fields of DCB - SetCommState(DCB) As in synaser, actually. Perhaps you could test what happens if you replace the command FillChar(...) by GetCommState(...) HTH, pf There is a bug (well, an unimplemented part of code) in file synaser.pas, in method TBlockSerial.cpomComportAccessible, in the orphan lock remove part. There is call to Libc.getsid, when not fpc and then removal lock file. in fpc (we are in fpc, arent'we?) there is NOTHING. So, there is already function FPGetSid, so we change the test to: if Libc.getsid(ReadLockFile) = -1 then ... to if FPGetSid(ReadLockFile) = -1 then ... and remove unnecessary ifdef fpc braces (I guess - but I have removed them) - the whole thing begins to work with no(? - so far - so good) hassle.

Well that's fine:
It is the stopbit - see the constants in the synaser unit.

1 = 1 1/2 stopbit
2 = 2 stopbits
It is an enumeration.

Re: [Synalist] SynaSer - timing problem?
Hi all, I want to use one serial port for writing to and reading from two different devices. Therefore I wanted to open the port for reading and then close it again. I have tried the following for the reading part: PROCEDURE lesen; var ser: TBlockSerial; begin repeat ser:=TBlockSerial.Create; ser.ConvertLineEnd := true; ser.Connect(port1); data := ser.Recvstring(1000); writeln(data); ser.free; until keypressed; end; (The variable data will be exported to the program later). Unfortunately the variable data contains only the last 10 to 15 characters (data has the type string[25]). It seemst to be a timing problem. I have put a delay(500) before/after or both the data := ...-expression, but without any positive results. Where is the mistake? Thank you!

Re: [Synalist] SynaSer {solved}
{:stopbit value for 1 stopbit}
SB1 = 0;
OK, there I had something wrong in my mind. Sorry, but I relied too
strong on my mind instead of looking it up.
{:stopbit value for 1.5 stopbit}
SB1andHalf = 1;
{:stopbit value for 2 stopbits}
SB2 = 2;
It works as it should, thanks to all contributors! The serial port I
used didn't work (though SynaSer showed an OK-status), hardware
problem. I tried the other port and everything was fine...
Thank you!

Re: [Synalist] SynaSer
True, guess that is the case if you are supporting a free product. Here is some information on the synapse components as well (to so much synaser): http://www.dubaron.com/synapsecookbook/ Also, when searching the forums you should also find some information. The documentation on the procedures in the Synapse / Synaser is not to bad either once you know what you are looking for. Alternativily, examine the examples that is provided. Perhaps Lukas or someone else can direct you to some more links. Based on you question and the information you have gathered thus far, anything else you need to know, maybe I can help?

Re: [Synalist] SynaSer
Based on you question and the information you have gathered thus far,
anything else you need to know, maybe I can help?
Thank you for this offer!
I don't know if this mailing list accepts attachments so I have copied
the program serialtest.pas at the end of this mail.
I have connected my sending unit with my PC on /dev/ttyS1. This unit
sends data, I have checked this with a terminal program. The parameters
are 9600, 8N1. The data consist of a string (ASCII) with 21 characters,
followed by two LF (dec.10). It is sent every 2 s, sometimes 1 s.
Now I've looked to the rs232_connect-procedure. The loop
repeat
write(ser.recvbyte(1000), ' ');
until keypressed;
should result in showing the received bytes on the screen. But all I
get is 0 0 0 0..., even, if the unit is switched off.
I am sorry, but the study of the definitions of RecvByte in the
SynaSer-unit didn't help me (function TBlockSerial.RecvByte...).
Is it a timeout, which is to small?
I hope, I made it clear to you.
Any help appreciated!
Richard

Re: [Synalist] synaser tries to use write protected directory /var/lock
Under Linux TBlockSerial class tries to use write lock file /var/lock/LCK..ttyACM0. But the user haven't permissions to write to this dir. What is correct way to workaround this trouble? The possible ways are: 1). Edit synaser.pas unit and point another dir for lock file. 2). Allow user to write to /var/lock dir. -- ... or read the documentation (or sources!) and set LinuxLock property to false. ;-) -- Lukas Gebauer.

Re: [Synalist] synaser as service Problems
Lloyd Thomas wrote: I don't understand where I am going wrong, but I have the following code in a windows app and a service. When I run the app in idle it uses 0% cpu, but if I run the service it uses 50% of the CPU. If I change the var activeport := false, (as to not receive serial data) the service falls back to using 0% cpu. Can someone advise what to do? Why the difference between an app and a service? You're not deferring to other threads in your main loop... inserting a Sleep(1); line just before until false; should do the trick. Regards, Ulrich - This SF.net email is sponsored by: Splunk Inc.

Re: [Synalist] synaser example
No response yet, But i have simplified my code as 'terminated' cause a problem. So while the new code will run I get an error after the Recvstring timeout. 'ESynaSerError with message 'Communication error 9997' Timeout during operation'. What does this mean? It meaning - no reqested datas are received during your timeout. RecvString expecting each line terminated by CRLF, and you maybe have different terminator in real data stream. So, Synaser waiting for CRLF what not incomming... and raise timeout error. -- Lukas Gebauer.

Probably because of the ser.RaiseExcept := True statement. Try it
without this.
What does this mean?
How can I improve my simple code?
code as follows

program dataser;

uses

try

if ser.lastError0 then exit;

finally
ser.Free;

Hi,
I wish to use synaser to capture text sent to a serial port. I do not
have a test facilty at the moment, so I need a little help to make sure
I am going in the right direction.
The basic code I have is as follows.
code--
{$MODE DELPHI}
Program testser;
uses
synaser, sysutils;
var
ser:TBlockSerial;
LCMD:String;
begin
ser:=TBlockserial.Create;
try
ser.RaiseExcept:=True;
ser.Connect('COM1');
ser.Config(9600,8,'N',0,false,false);
with ser do
begin
repeat
if terminated then break;
LCMD := RecvString(1000);
if lastError0 then break;
writeLn('LCMD');
if lastError0 then break;
until false;
end;
finally
ser.Free;
end;
end.
End of code--
Does this look OK?
If not, how should I do this?

Re: [Synalist] Synaser for FreePascal
So, I made new Synaser version what have removed Libc dependency on FreePascal, and count of needed modifications is much smaller then in Charlie case, and result code is cleaner. I publish this new Synaser version in next Synasnap, please, test it! right, I hope to try it next week. Thanks for it. Jose Pascual -- Lukas Gebauer.

Re: [Synalist] Synaser AtTimeout and GSM
problem with error 9997 resolved with: ser-AtTimeout = 4000;. It is minimum for correct functional. GSM Module Siemens MC55. But, I tried another component for com port communication (TComPort) and there is not problem with timeouts. And of cource when I send SMS via TComPort I got it faster than via Synaser. So problem is not is HW of mobile, but in library I thing. Or not? How you are implementing it by TComPort? It have sme special AT command support? I think not, so you are implementing it by direct port sending and reading, right? Then try to implement it by same way in Synaser too. I not know how exactly is SMS sended by AT command, where and what is expected by modem and what by computer. AtCommand is just helper function for easy sending simple AT command and it maybe not effective in your case. But you allways can implement what you need by sending and receiving functions in Synaser. There is not reason why Synaser will be slower in this case, just impelment it by similar way as in TComPort and then compare. -- Lukas Gebauer.
