Serial Port commmunications

[Hugo]

Hi everyone!

I need your help! I'm writting a program to comunicates a PC with a
PinPad trought serial port... I'm using _bios_serialcom from bios.h...
But when I tried to send some data it doesn't work and the return code
from _bios_serialcom starts with 8... I don't know what I'm doing
wrong... Any help would be appreciate!

Here is my fuction sendcommand:

sendcommand(unsigned serial_port, char *pString, short nStringLen)
{
short i;
short nComStatus;

for(i = 0; i < nStringLen; i++)
nComStatus = _bios_serialcom(_COM_SEND, serial_port, pString[i]);

return(nComStatus);
}
Thanks in advance!

Since the standard C language knows not of concepts like `serial port',
you'll have to ask this in a forum specific to your platform.[1]

HTH,

[1] Had you read the FAQ (easily found, GIYF) or lurked (as any
prospective poster should) you would have known this. Now you do.

Standard C (which is what we discus here) does not have bios.h or
_bios_serialcom. You need to ask in a group dedicated to your system
whatever that may be. For more information on this group, see the link
in my sig and the other things it links to.
