Microprocessor RS-232 Reset - This circuit allows a remote microprocessor to
be reset by a controlling host by sending a break signal over an RS-232 or RS-422
serial line. If the remote machine resets into a simple program loader program, it is
possible for the host to halt and restart, or halt and reload/restart the remote
machine's program. This is an ideal way to develop software on older EPROM-based
systems. Modern EEPROM/NVRAM systems use JTAG interfaces for similar
results....(electronic circuit added 7/03) |
