Serial port rs232 comunication bi-directional mode maby php and visual basic
Hi, I need some Best ideas for a project that I am building,
I need create a standart way software solution to comunicate with many medicaL instruments,
like : ADVIA,CELL DYN, COBAS, PENTRA, CENTAUR, etc,
each instruments have their own standart data code comunication,
like :ABX,ASTM,H7,CVS,ARGOS,etc
the protocol comunication to all instruments is the same:
RS232 NULL MODEM db9 or db25 PINOUT, I have not ptoblems with the phical layer.
how this work:
intrument ask to pc for a worklist, pc send worklist data
when the instrument has finished all worklist task send the results back to pc.
the solutions that I am thinking is:
1.- Develop all in php, but can php listen in com1 in windows enviroment?
2.- create an visual basic script, for manage the serial comunication data as a proxy, and find the best way to integrate this application to php( that php processe requested data, making conection to database.
in this case is an hibrid solution

I have written many apps using RS232 back in the old days way back in 76. Under Windows the problem with RS232 was a physical limit to the devices that you could connect to. But using USB and some kind of driver this limit may have been overcome.
What type of physical connection system are you going to use? Does it have any limits?

the application will be installed for manage one unique serial port this ou focos for simplicity.
that for each serial port we need only clone the aplication and install, normally each pc have 3 instruments not more, but not have limitation.

nice model, this is very pointting in the rigth way, in this midle time, I have aready made same decision:
-Clients will have an small exe, acting as a port gateway serial/tcp in bi-directional mode, listen for connection started from any side. I have writed 90%
-Server willbe an php socket server runing in linux as a backgound process. 10% only for test.
and here we are posting this asks for this:
https://www.experts-exchange.com/questions/26868024/php-socket-server-handler.html
-At server side we are searching a create a standard way for normatize all direntes fiels coming from all devices, if you wan I have opened another post about this here:
https://www.experts-exchange.com/questions/26868015/php-ASTM-protocol-standard-parser.html
in general, what is the best for manage rs232 basic data comunication?
in the small exe, (like ACK ENQ commands response interacting for data transmition) or at the tcp server we do all control data as the ACK ENQ and all data adquisition/tramsmition.

B: The Expert(s) provided an acceptable solution, or a link to an acceptable solution. May assign if you needed a bit more information to complete the task.
seach for com1 and you will see some code that shows you how to write to COM1. This may help you get started.
