Register parameters

RST 20H, DEFW $200C
IN:
    HL = SOH buffer address in the screen base file
    B = screen base file bank

OUT: 
    Fc = 0, success
    FC = 1, A = RC_Eof : No CLI running

Registers changed after return:
    ..BCDEHL/IXIY same
    AF....../.... different

Notes

Internal operating system usage.

Call used to disable printer redirection on SOH escape sequence containing '['. Printer redirection is enabled if the sequence contain ']'. It avoids to send rubbish to printer during CLI redirection, for example the sequence 1, '2', '.', '[' is sent before window definition of the Filer and 1, '2', '.', ']' is sent after.
