Hi.
The following code will achieve what you want:
   eg:
      SerialIO->IOSer.io_Command = CMD_READ;
      SerialIO->IOSer  .... etc
      SendIO(SerialIO);           /* Start IO but do not wait */        
      Wait( SIGBREAKF_CTRL_C | 1L << SerialMP->mp_SigBit); 

      SerialMP is a pointer to the message port associated with your 
      IOExtSer or whatever.

This waits on the signal bit of the message port (which is set when
the device "Replys" to your IO request) OR the CTRL-C Signal.
