Need 2 API calls

[mbaddar]

Hi

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?

Desperate!!!

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

Hi,

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

Thanks,

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&quot.
Anyway, the sequence is usually platform-dependent and is defined in the library's header files.
