What Tony is talking about isn't actually serial commands but Hijack macros, i think, which aren't quite the same and have different timing aspects.
No, I'm talking about serial commmands. Can be done without hijack.
HOWEVER, I have just noticed there is a bug in it. I don't know if this bug is Hijack's fault or not:The documentation for the serial commands says that N and P should be next/previous in the menu. This is not working currently. You can enter the menu structure with M, but after that, N and P don't work any more.
Also, the seek commands (f and b) have a problem in that I can't seem to stop them once initiated.
Empeg Guys? Is this yours?
