Only using the pure System API? As long as you don't want to set
comm parameters (speed, databits, parity): Yes. Just do an

char comm_dev[80];
int const comm_nr;

#ifdef WIN32
#define COMM "COM%d"
#elseif
#define COMM "/dev/ttyS%d"
#endif

sprintf(comm_dev, COMM, comm_nr);
FILE *comm_f=fopen(comm_dev, "w+");

// your comm here

fclose(comm_f);

However if you want to set comm parameteres you will have to use
an OS dependent API. For windows that means that you will have
to use it's ugly file API.

Sort of.... It you use the Qt-toolkit, there is an extension called
QExtSerialPort that provides what youŕe looking for.
