You should be able to do an OPEN(file="COM3",...) and do very basic things with the RTL. For more sophisticated work the Win32 routines really aren't hard to use, it depends on the kind of I/O you are planning to do.<BR /><BR />James Wed, 05 Mar 2003 15:48:25 GMT james1 2003-03-05T15:48:25Z https://community.intel.com/t5/Intel-Fortran-Compiler/Serial-Port-IO/m-p/820506#M47435 Hi, <BR /><BR /> On VAX fortran I could do an OPEN(file="TTA0:",...)<BR />and open the a serial port for READ/WRITE.. I'm trying to see that I can do the same with Intel Fortran V7.0 before I start coding my sample project. I have a Windows2000 system with 6 COM ports and need to open all of them for READ/WRITE access. <BR /><BR />I've searced the forum and found references to SPORT_xxx routines but can't find them described in the three manuals for Fortran on the web site? <BR /><BR />Is there a pointer to an example?<BR /><BR />Thanks,<BR />Jon Crowell<BR /> Wed, 05 Mar 2003 10:56:50 GMT https://community.intel.com/t5/Intel-Fortran-Compiler/Serial-Port-IO/m-p/820506#M47435 joncrowell 2003-03-05T10:56:50Z https://community.intel.com/t5/Intel-Fortran-Compiler/Serial-Port-IO/m-p/820507#M47436 I think the SPORT routines are CVF.
