| String problem with one more ENTER |

Hello
to select Write or Read data from RS232 to EEPROM, I have two functions like this:
WRITE TO EEPROM
| Code: |
void anexoW(){
fprintf(COM_A, "\r\nMens Liga: ");
get_string(string, ROM_MENS_LIGA_SIZE);
write_eeprom_string(string, ROM_MENS_LIGA, ROM_MENS_LIGA_SIZE);
fprintf(COM_A, "\r\nMens Desl: ");
get_string(string, ROM_MENS_DESL_SIZE);
write_eeprom_string(string, ROM_MENS_DESL, ROM_MENS_DESL_SIZE);
//...
fprintf(COM_A, "\r\nSaved\r\n");
}
|
READ FROM EEPROM
| Code: |
void anexoR(){
read_eeprom_string(s, ROM_EPASSW, ROM_EPASSW_SIZE);
fprintf(COM_A,"AT#EPASSW=\"%s\"\r\n",s);
//...
read_eeprom_string(s, ROM_EADDR, ROM_EADDR_SIZE);
fprintf(COM_A,"AT#EADDR=\"%s\"\r\n",s);
}
|
But when I call to anexoW(), never back to principal program, needs one more Enter to back. I have in my principal program a real time clock with interrupt and STOP.
I do not understand, why needs a Enter.
Thank you Carlos |

I've had this problem before, not only on PIC stuff, but also PowerPC-based routers and PBXes that use serial lines to a PC or Linux workstation.
You can eliminate the extra carriage return necessary by putting in a:
This will "eat" up the pending carriage return.

p.s. I'm not sure why it does it, but may be something to do with Hyperterminal (Windows), Kermit (Linux/Unix), etc. I'm shooting in the air, but i think it can be described as "raw" or "cooked" mode for your terminal i/o. |

To be more specific,
put a "getchar()" exactly after your getstring() function call. |
