ZCOM Status Codes
Terminal I/O Status Codes
Chapter 3 63
IO_TX_URUN(08) Transmit underrun
The multiplexer could not supply data fast enough to
keep the transmitter running. With a character
oriented synchronous protocol this will usually result
in SYNC characters being inserted. With a bit oriented
synchronous protocol the frame being transmitted will
be aborted.
IO_INV_RESP(09) Invalid terminal response
The remote device has responded with a message
which is invalid in the current state.
IO_PROT_REJ(10) Protocol rejects request
The protocol does not handle this type of request.
IO_LONG_MSG(11) Message too long
If this applies to a transmitted message then it is
probably too long to be able to complete within the
transmit timeout. A received message may be too long
for the allocated number of receive buffers, or may take
too long to complete.
IO_SHRT_MSG(12) Message too short
The message is less than the minimum allowed length
for this protocol.
IO_POLL(13) Host has stopped polling
Only used for secondary protocols. The protocol has
waited too long for a poll or select from the remote
device.
IO_BCC_ERR(14) BCC or CRC error
A message was received with a bad checksum.
IO_PARITY(15) Parity or framing error
A message was received with a bad parity bit or an
asynchronous character was received with a frame
problem.
