break up string to multiple variables

I have a serial input. the code below reads each byte and checks if its the start ($) or stop (#) bits. Takes string of chars and puts it in a variable.
I actually need to get 2 variables out of this and I cant figure out how to split it.
so if my input is $abc|def#
I currently would get string=abc|def

I want:
string=abc
string2=def

char string[66];
int curWritePos;
int availableBytes = Serial.available();
    if (availableBytes > 0)
    {
        for(int i=0; i<availableBytes; i++) 
        {
           int ch = Serial.read();
           switch(ch)
           {
               case '#':
                 //  Serial.println(string);
                   displaycrap(); 
                   curWritePos=0;
                   string[curWritePos]=0;
                   break;
               case '$':
                   curWritePos=0;
                   string[curWritePos]=0;
                   break;
                      
               default:
                   if (curWritePos < sizeof(string)-1)
                   {
                       string[curWritePos++]=ch;
                       string[curWritePos]=0;
                   }
                   else
                   {
               //        Serial.println("Overflow\n");
                   }
                   break;
           }

Find an equivalent program below:

#include <stdio.h>
#include <string.h>
#include <curses.h>

void splitAndPrint(char inStr[]);
int main(int argc, char *argv[]) {
char string[66];
int curWritePos;
int c;
int charNo = 0;

while (1) {
c = fgetc(stdin);
if (c == '$') {
curWritePos = 0;
while (1) {
c = fgetc(stdin);
if (c == '#') {
string[curWritePos] = '\0';
splitAndPrint(string);
break;
} else {
string[curWritePos++] = c;
}
}
}
}
}
void splitAndPrint(char inStr[]) {
char *delimPosition;
delimPosition = strstr(inStr, "|");

*delimPosition = '\0';
printf("string = %s\nstring2 = %s\n", inStr, delimPosition + 1);
}

Output from the program below:
/home/sbiswas/c> ./test
$This|That#
string = This
string2 = That
$His|Hers#
string = His
string2 = Hers
$Now|Then#
string = Now
string2 = Then
$First|Last#
string = First
string2 = Last
