Error while enabling AT via AT!USBCOMP on WP7607

why don’t you use “microcom /dev/ttyAT” to enter AT command directly?

Thanks. That works.
But I am just curious if it’s not too complicated to get to this data in this way.
connect to console port, then login, then use microcom to /dev/ttyAT
Wouldn’t it be much easier to allow AT for at!usbcomp ?
Regards.
