Hi,

Trying to control some GPIO pins on RPI4. It works with ggee/shell external and the pinctrl command.

However if I send multiple pinctrl commands in a short timespan some are dropped. Also, running pinctrl set 5.6.13 op dl for example does not work (it should pull low those three outputs at once and works in the terminal just fine) But PD also automagically adds spaces after the commas once the message box is not edited anymore.

Are these known limitations of shell or is there a workaround to run multiple commands at once? Adding & or ; to the end of the message sent to shell does not work...
