 		 #166066 - HyperTerminal & ASCII code
Responding to: ???'s previous message
Thanks guy,

Yes, I know that when the printer power up, if there is no RS232 cable connected to it and I did make sure that.

I very much suspect that "BEL" means the single ASCII code 0x07; not the 3-character string "BEL" - are you sure that Hypoterminal is actually sending the ASCII BEL code?

To be honest I get confuse about the meaning of those commands. Should I send characters "BEL" or "07"? Yes, I will try to use their sample codes with Q-Basic.

In terms of what the hyperterminal sending, I did try to send characters "BEL" from my MCU to the PC and did see them on the terminal, but I have not tried other way around.

So say if I am successful of controlling the printer from PC, would it be realistic to connect the printer to and print out data from MCU (8051)?
