It is configured via the command definition macro on a per-command basis. "Dangerous" commands do *not* repeat, commands that may be useful to repeat (e.g. displaying memory) do. Hey, you were just complaining that you had to retype the IP address for repeated pings - now you are complaining that you don't have to type anything to repeat a command.

Also, on commands like memory display, it auto-advances the address so that you can hit <return> multiple times to see the next chunk of memory. Command history requires you to edit the address manually to get the next chunk. (FWIIW, I would be happy to see most command repeats turned off, but memory display auto-advance is really nice.) gvb ^ permalink raw reply [flat|nested] 8+ messages in thread

Before I discovered this was a feature, I was sure this was a bug, but I understand some of you reasoning.. just not all. For instance, I can understand why it's handy when dumping memory, but what's the rationale behind having 'cp.b' repeating? It's annoying when writing large files to slow (NOR) flash.

Indeed it is. IMHO, rather than select a few "dangerous" commands to exempt from autorepeat, it should be off for most commands and selectively enabled for a handful of commands where it's really useful (such as autoincrement dumps). -Scott ^ permalink raw reply [flat|nested] 8+ messages in thread
