#SERIAL PORT PROBLEM
I am having trouble reading from the serial port. I have two test
programs one sends data out of the serial port and the other reads data from
the serial port. I run the two programs together and use the modem to mirror
the output back for the input program to read. This works fine.
Now I have added a wait function to wake up when anything arrives at
the serial port. Now the program will not work. The information is read if the
wait is satisfied with a CTRL_F but appears not to recieve the serialMP message
or it ignores it.
Below is the gist of the wait and read section. Can anyone tell me what
I am doing wrong? Thanks in advance.

WaitMask = SIGBREAKF_CTRL_C| SIGBREAKF_CTRL_F|1L << serialMP->mp_SigBit;
while (continueloop) {
waitsignalsreturn = Wait(WaitMask);
if( SIGBREAKF_CTRL_C & waitsignalsreturn)
{
continueloop = FALSE;
break;
}
serialIO->IOSer.io_Command = SDCMD_QUERY;
DoIO((struct IORequest *)serialIO);
lengh = serialIO->IOSer.io_Actual;
serialIO->IOSer.io_Command = CMD_READ;
serialIO->IOSer.io_Length = lengh;
serialIO->IOSer.io_Data = SerialReadBuffer;
DoIO((struct IORequest *)serialIO);
printf("%s",SerialReadBuffer);
}
