; Version 1.2 - 2012 Roman Borik
;
; New in version 1.2
; - Support for undocumented 8085 instructions.
; DSUB B, ARHL, RDEL, LDHI d8, LDSI d8, LHLX D, SHLX D, JNK a16, JK a16, RSTV
; - Command R displays all flags of F register (SZKA3PVC). If flag is not set
; dash '-' is displayed.
; - Added restart vector RST 8 (0040h) for possibility to handle RSTV call.
; - Changed TRACE mode. After entering TRACE mode, instruction on actual PC and
; content of registers (if it is switched on) are displayed.
; Entering a space ' ' executes this instruction, and returns to the 'T>'
; prompt with the next instruction.
; - Instructions LXI, DAD, INX, DCX displays argument 'SP' rather than 'S'.
; - Commands that requires 1 byte parameter raises error if entered value
; not fit to 1 byte.
; - Command 'C' checks overlap of source and destination block and for copying
; uses appropriate direction.
; - Command 'F' checks <start> and <end> parameters and raises error,
; if <end> is lower than <start>.
; - Added command 'H' to send out memory content in Intel HEX format.
; - Sending of LF and CR characters were reversed and are sent in the usual
; order - CR first and followed by LF.
