TLazSerial : serial port component for Lazarus (windows and linux).

[avra]

I have installed Lazarus 1.0.6 on the PC and LazSerial installs fine and the test app works. However, nowhere can I find out clearly how to install 1.0.6 on the Raspberry Pi with Raspbian. apt-get install lazarus gives me the same 0.9.28.2 version, so I seem stuck!

The link I gave says this:

...you might try to install FPC from repository, and then install Laz 1.0.6 from source (I think that was the last version that could be compiled with FPC 2.6.0)

This means that FPC is installed through apt-get (as you already did), and Lazarus from source as in wiki described here:
http://wiki.lazarus.freepascal.org/Installing_Lazarus#Downloading_Lazarus_Source_Code. You need to have subversion installed first, of course.

This might also help:

Hi, Thanks for that. In the second link, I see that he installs fpc 2.6.0 from the repository, then updates it to 2.7 and then installs Lazarus 1.0.6. He provides 2 scripts to do this but I gather they have mistakes in them! I will give it a try with a fresh installation of Raspbian as soon as I get the time. Thanks for your help. I did also have the thought that the gps daemon makes the gps info available at local port 2947. Is there a function in fpc to open a local port? That saves messing around with USB!

Likely to be a dumb question, but where I could download TLazSerial from?

I'm in the process to migrate my Delphi stuff into Lazarus and quite not yet familiar with the structure of the different resources.

Thanks in advance! Pedro

If you are using a raspi, forget TLazSerial as it won't install. Nor will 5dpo!!

hello,
if you are on Windows or linux and with Lazarus >= 1.x  , look at the first post of this topic and read the how to install.

Friendly J.P

Try Synaser from synapse.ararat.cz, or just use FPC serial unit instead (search for serial.pp file since that's all docs you will get for it).

Thanks ever so much, I've been looking for such a component since a year!! nice work. Just installed and tested on CodeTypon 4.41.

i don't have serial port, how can i make port like you use '/dev/pts/5' ? i'm in linuxmint.

hello,

1 - install socat in your linux distro
2 - launch this command in a terminal :

Code: [Select]

socat -d -d PTY: PTY:if it is good you can see in your terminal window something like this :

2013/08/20 03:41:03 socat[4275] N PTY is /dev/pts/5
2013/08/20 03:41:03 socat[4275] N PTY is /dev/pts/6
2013/08/20 03:41:03 socat[4275] N starting data transfer loop with FDs [3,3] and [5,5]

if you have successfully compiled the example of lazserial  sertest:
1 -  launch sertest
2 - in port settings/port enter your first virtual serial port ( ex for me /dev/pts/5)  don't use combo button because virtual serial ports are not detected)
3 - close the port settings window and click on the open button.

4 - launch another sertest
5 - in port settings/port enter your second virtual serial port ( ex for me /dev/pts/6)
6 - close the port settings window and click on the open button.

7 - in your first sertest check RMC and click on the start simulator button.
8 - if all is good , you can see RMC frames in the memo of the second sertest  like this :

$GPRMC,035654,A,4851.184,N,00220.977,E,000.5,054.7,200813,020.3,E*71

friendly, J.P

thanks.

other question:
I have a Epson Tm 70 connect to Usb, and have virtual port ESDPRT001, can I use Lazserial to communicate with it?

Dear friend, have a good day from Athens - Greece.

Can you please provide me the link for the component?

Many many thanks

I'd like to port www.CtrlTerm.com to LazSerial and Lazarus, so if anyone sends me code I will consider publishing it.

Hi jurassic do you know how to emulate delay line and delay character with synaser, i sow documentation but only one function is  about delay time , sorry for my topic?

thanks.

Mr. Pork,
I tried several libs, before getting to this one, and the good thing about is that it really works.
What bothers me is that usually a timeout can be set, but I saw nothing like that in TLazSerial.

I tried to compile lazserial on mac and send this error
