Syntax
'EO'
Description
The 'EO' mnemonic turns off output transparency set by the 'BO'mnemonic. When transparency is on, all data is passed through the device driver without translation except for 'EO' and 'RM', to prevent interception of characters that are special characters to the driver, such as ESC. PRO/5 sends standard mnemonics as $1B$ (ESCAPE) plus the two-character mnemonic. Long mnemonics are sent as $1B$, plus a length byte, plus the characters representing the mnemonic. Use of output transparency usually invalidates the buffering maintained by PRO/5 and requires an'RS'(Refresh Screen) mnemonic to restore coherency.
