Question on system command 1.4.43
.... pl2303: Prolific
PL2303 USB to serial adaptor driver
if I login to the box and send/receive serial commands over this unit it
works without error EVERY time.
however, if I run the same command set from with-in the extensions.conf
with System()
I get errors in dmesg like "pl2303 ttyUSB0: pl2303_open - failed
submitting read urb, error -22"
and then obviusly my command does not work.
however, again - If I go back to the command line and my command it runs
just fine.
Any ideas on what might be happening here?
