Examples

#include "mbed.h"
#include "iSerial.h"

char s[] = "12345678901234567890123456789012345678901234567890";

int main() {

    iSerial pc(USBTX,USBRX);
    char* c = s;

    while(1) {
        pc.puts(s);
        
        while(pc.readable()){
            int ret = pc.getc();
            if(ret)
                *c++ = ret;
            if(c >= s+sizeof(s)-1)
                c = s;
        }
        wait(1);

Comparing speed of ordinary Serial functions

#include "mbed.h"

char s[] = "12345678901234567890123456789012345678901234567890";    // 50 bytes

    iSerial ipc(USBTX,USBRX,NULL,1000,100); // try NOT to set the buffer over flowed
//    iSerial ipc(USBTX,USBRX);   // set as default = 100, 100
