To be sure that I send correct commands to the printer, I connected it to my PC via serial port then set all setting required (e.g. BAUD rate, parity, etc...) in HyperTerminal. Good plan, but Hypoterminal may not be a good tool here... I sent commands like "BEL", or "ESC RS" or "LF" to test to see if the printer execute those. But nothing happened. Are you sure those commands were actually sent correctly by Hypoterminal? 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? Similarly ESC is probably the 'Escape' code, 0x1B - pressing the key marked 'ESC' on the PC's keyboard may or may not cause Hypoterminal to send an 'Escape' character... |
