SunOS 5.5 Devices stc(7D)

ppc_acktimeout: unit %d ACK timeout

ERROR. The ACK line from the device connected to the parallel port did not

assert itself within the conﬁgurable timeout period; check to be sure that the

device is connected and powered on.

ppc_acktimeout: unit %d BUSY timeout

ERROR. The BUSY line from the device connected to the parallel port did not

de-assert itself within the conﬁgurable timeout period; check to be sure that

the device is connected and powered on.

ppc_int: unit %d stray interrupt

ADVISORY. The parallel port controller ( ppc) chip generated an interrupt

while the device was closed; this was unexpected and if you see it frequently,

your parallel cable might be picking up induced noise causing the ppc to gen-

erate an unwanted interrupt, or this could indicate that the ppc might have an

internal problem.

ppc_acktimeout: unit %d can’t get pointer to read q

ERROR. Somehow the driver’s internal ppc data structure became corrupted;

this should not happen.

ppc_acktimeout: unit %d can’t send M_ERROR message

ERROR. The driver can’t send anM_ERROR STREAMS message to the appli-

cation; this should not happeneither.

ppc_signal: unit %d can’t get pointer to read q

ERROR. Somehow the driver’s internal ppc data structure became corrupted;

this should also not happen.

ppc_signal: unit %d can’t send M_PCSIG(PP_SIGTYPE 0x%x) message

ERROR. The driver can’t send anM_PCSIG STREAMS message to the applica-

tion (which could cause a signal to be posted); this should also not happen

either.

STREAMS

Processing:

stc_wput: unit %d trying to M_STARTI on ppc or control device

ADVISORY.AnM_STARTI STREAMS message was sent to the parallel port or

the board control device; this should only happen if an application explictly

sends this message.

stc_wput: unit %d line %d unknown message: 0x%x

ADVISORY. An unknownSTREAMS message was sent to the driver; check

your application coding.

stc_start: unit %d line %d unknown message: 0x%x

ADVISORY. An unknownSTREAMS message was sent to the driver; check

your application coding.

Serial Port Control:

stc_ioctl: unit %d line %d can’t allocate streams buffer for ioctl

ERROR. The driver could not get aSTREAMS message buffer from bufcall()

for the requested ioctl; the ioctl will not be executed
