Readers particularly interested in this area should look at the current development version of GDB and the discussions in the various GDB newsgroups. The serial connection is usually established on the first call to getDebugChar.

This minimizes the risk of a program being left with breakpoints inserted, for example when a serial link fails. Caution In the RSPthe s packet indicates stepping of a single machine instruction, not a high level statement.
