Need 2 API calls


I'd like to know if there are a couple of API calls
out there that I can use. I need one to send
a carriage return and another to read data from
a serial port. Does anyone know if these exist?



RE: Need 2 API calls

You can use
            fSerialPort = fopen("COM1", "r");
            fgets(szILine, sizeof(szILine), fSerialPort);
Please let me know your results.....

RE: Need 2 API calls


Thanks, okay, that looks pretty easy. Is the "r" the way
to send a carriage return in VB?


RE: Need 2 API calls

No, the "r" is for "read" because you want to open the port
for a read operation.
If you want to send a carriage-return somewhere (e.g. to a port), open the port with "w" for "write" and use any write
function like WriteFile to write the correct ascii sequence
(maybe you will recognize the term "escape sequence").
Anyway, the sequence is usually platform-dependent and is defined in the library's header files.

RE: Need 2 API calls


Okay, thanks for the clarification.
