The 3215 virtual console presented to Linux by z/VM is such a keyboard printer. If you connect with a 3270 (or emulator), VM uses fields on the 3270 screen for pre-defined input and output areas. The guest operating system only sees lines (or "records") and the console driver in Linux translates between ASCII and EBCDIC. If there is any flaw with the translation, it is only that Linux should treat "EBCDIC" as Codepage 1047. If there is any lack of Unixiness (eg: cannot run 'vi'), it is present in any "keyboard printer" whether that is an ASCII animal or a mainframe EBCDIC critter. -- R; John Summerfield <[EMAIL PROTECTED]> Sent by: Linux on 390 Port <[email protected]> 09/29/2006 07:01 PM Please respond to Linux on 390 Port <[email protected]> From John Summerfield <[EMAIL PROTECTED]> To [email protected] cc Subject Re: zLinux User Passwords on console Pieter Harder wrote: > I keep wondering about all this insistence on emulation etc. > There must be something in between the HMC ASCII console (one per LPAR), and total emulation in software (capable of running thousands) > _I_ was suggesting a device that VM might emulate (present to Linux as a virtual keyboard-printer), and that being start/stop. might actually work well with Linux.
