# Why not use "openct-tool rwait" instead of polling opensc-tool exit status?
|
|
# Well openct daemon has to be running which interferes with pcscd since both
|
|
# implement reader drivers, my particular CCID reader (SCM SCR331-LC1) doesn't
|
|
# work with the CCID driver in openct, however it does work with pcscd.
|
|
|
|
# Why not use "opensc-tool --wait" instead of polling opensc-tool exit status?
|
|
# Although opensc-tool --help reports that there is a --wait option, it doesn't
|
|
# seem to be implemented.
|
|
|
|
# Load configuration and test set default value if missing
