To address this, add the following line to /etc/iu.ap file. -1 0 ldterm ttcompat ( could be usbsprl, usbsksp or usbser_edge ) Run the following command and ignore error messages : # autopush -f /etc/iu.ap Connect USB serial device to the system. Run the following command to verify ldterm and ttcompat modules have been pushed on top of the usb serial driver: # strconf < /dev/term/0 The output should look like: ttcompat ldterm Now, try your application again.
