zshn: not initialized, can’t send message
An M_DATA message was passed to the driver for a channel that had not
been programmed at least once since the driver was loaded. The SCC’s regis-
ters were in an unknown state. The S_IOCSETMODE ioctl command performs
the programming operation.
zshn: transmit hung
The transmitter was not successfully restarted after the watchdog timer
expired.
