data transfer from port

[Erik D]

Hey,
Does anyone know if there is something in C that can read the data transfer
in the serial/paralel-port?
Or can't that be done with C?

THX, Erik

Who knows this is a C++ group. Try news:comp.lang.c, I suspect that the
answer will be, 'It depends on your operating system' (pretty obvious
really), so why not try a group about whatever operating system you happen
to be using.

Reading from the serial, parallel, USB, I2C, and Firewire ports can
be read from C and C++ with a little help from platform specific
functions.

Reading from the serial port could be as easy as:
char read_serial_port(void)
{
volatile char * Uart_rx_reg = (volatile char *)(0x43000);
return *Uart_rx_reg;
}

But then, it could be more complicated, especially if your
platform doesn't have a serial port.

By the way, some serial ports are different than the
parallel ports.

In fact, he already posted there and got pretty much that response.
Demonstrates an appalling lack of usenet skills, as he multiposted to
groups, posted in the wrong groups, did not lurk for the required time,
blah blah blah.
