A Target MCU is restored to a Target State. A Host Trace of Debug Commands is preserved as the Target MCU is driven from a known first state to the Target State by executing a series of Debug Commands. The Target MCU is then reinitialized to the known first state. The Debug Commands are read from the Host Trace and sent to a Modular Development System (MDS) for execution by the Target MCU until the Target MCU is again is driven to the Target State.

A Host Debugger and a Modular Development System (MDS) are dynamically reconfigured. The Host Debugger queries the MDS for the identity of its Target MCU. The Host Debugger receives a message containing the Target MCU identity. The corresponding Host Debug and MDS environments are then loaded based on the received Target MCU identity.

A parser is dynamically reconfigured. Parse Control Records are read into memory. They are inserted into corresponding Parse Table Entries in a Parse Table in memory identified by a Parse Table Entry Identifier in each Parse Control Record. Each of the Parse Table Entries corresponds to a single command, and includes an ordered series of allowable parse states for that command. After a string of text has been tokenized into an ordered sequence of tokens, the ordered sequence of tokens is evaluated pursuant to the allowable parse states in the Parse Table Entries to determine whether the Text String has a valid syntax.

A copy of data in a Host Computer is synchronized with a version located in Shared Memory in a Modular Development System (MDS). Whenever a change in one or more bits in a Line of Data in Shared Memory are detected, a MDS Line Dirty Flag is checked. If the Flag is not set, it is set and a message is sent to the Host Computer that the Line of Data is now dirty. Whenever the Host Computer receives this message for a Line of Data in its visible memory, it sends a request to the MDS to read that Line from Shared Memory and send it to the Host. Otherwise, a Host Line Dirty Flag is set. The Host Computer also sends a request to read a Line of Data when that Line of Data is scrolled onto a screen and the corresponding Host Line Dirty Flag is set.
