 		 #152826 - Names? Delays?
Responding to: ???'s previous message
Eric Leung said:
Save This Code
GETCHAR: 
    		CLR A 
     		MOVC A, @A+DPTR         
     		INC DPTR 
     		JNZ SENDCHAR   		
     		RET


Why is this routine labelled "GETCHAR" - it doesn't seem to get anything!

Save This Code
RECEIVE_PROMPT:
	
		CALL SHORTDELAY		;wait for a moment	
		RET

Similarly, this doesn't actually receive anything!
Are you sure the delay is long enough?

It'd be far better to really read the response, and ensure that you actually do get the response before continuing...
