Serial port rs232 comunication bi-directional mode maby php and visual basic
Posted on 2011-02-27
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,
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
