Notes:	if the error flag in DH is set, the string is not sent and an error
	  message is generated instead; if this function is not called within
	  five seconds of AX=4504h, EMAIL automatically generates an error
	  message
	the string is copied into an internal buffer, allowing this function's
	  caller to continue immediately
