TCP to RS232 converter with Lazarus?

[Jurassic Pork]

hello,
for tcp server, you can have a look to the nxnetworktest project (which uses synapse) from nxpascal project :
1 - download last synapse stable version  and install lazarus synapse package (laz_synapse).
2 - from here download zip . Extract nxnetworktest (demos/fpc/nxnetworktest)
3 - add nxnetwork.pas (src/nxnetwork.pas ) in the folder
4 - add nxnetwork.pas to the project and laz_synapse as required package
5 - if you are under linux add -dUseCThreads to compiler options.

Friendly, J.P

using a TLazserial component in the Networktest project i can do this :
 listen the comport /dev/ttyUSB1 receiving GPS RMC NMEA frames .
when i have received a whole frame, send the frame to the TCP server.

Do it how to explain it Jurassic Pork.

1. Install lazarus Synapse package(library).
2. To establish connection and read data from serial device (RS232,RS485/422) use Synaser from Synapse (there is a example on wiki how to use it on Linux http://wiki.lazarus.freepascal.org/Hardware_Access) or TLazSerial.
3. Create a TCP/IP server using Synapse (you can found example(demo) in the package directory) or LNet (example of TCP/IP server also in package directory).
4. Share data from serial device to TCP/IP server inside you application.

It is really simple nothing hard.

Sorry for troubles with installing DataPort under Linux and lack of documentation.
