PDOS/390 just passes that through to the
application, but the applications are
expecting this:
static unsigned char atoe[256] = {
"\x00\x01\x02\x03\x37\x2D\x2E\x2F\x16\x05\x15\x0B\x0C\x0D\x0E\x0F"
"\x10\x11\x12\x13\x3C\x3D\x32\x26\x18\x19\x3F\x27\x1C\x1D\x1E\x1F"
Also I needed to add this table to micro-emacs:
static char mapctlbuf[256] = {
0x00, 'A' , 'B' , 'C' , 0x00, 'I' , 0x00, 0x00,
0x00, 0x00, 0x00, 'K' , 'L' , 'M' , 'N' , 'O' ,
'P' , 'Q' , 'R' , 'S' , 0x00, 'J' , 'H' , 0x00,
'X' , 'Y' , 0x00, 0x00, '\\', ']' , '^' , '_' ,
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 'W' , '[' ,
0x00, 0x00, 0x00, 0x00, 0x00, 'E' , 'F' , 'G' ,
0x00, 0x00, 'V' , 0x00, 0x00, 0x00, 0x00, 'D' ,
0x00, 0x00, 0x00, 0x00, 'T' , 'U' , 0x00, 'Z' ,
};
plus another one to reverse it.

Re: PDOS/390 on real hardware
I forgot to mention that since it is S/390, not z/Arch, it will need any processor from z13 back to S/370 XA. It only uses instructions contained in S/370 XA. Also, by "EBCDIC ANSI" terminal I mean something that will handle an ESC [ 2 J in EBCDIC instead of ASCII as a command to clear the screen. The PC that does the EBCDIC ANSI emulation would need to send keys up to the mainframe in bursts instead of waiting for the user to hit enter. So it may be necessary for the PC to emulate a controller too. BFN.
