Link status indicates whether the link is on, off, or starting. Starting indicates that a con-
nection command was received, but the link did not start because it did not receive the
data set ready (DSR) signal from the remote station. A line is off until it is started and
the DSR signal has been received from the remote station.
Current operation mode settings indicate whether the line can operate. A line is idle
when data transmission or reception can occur. The setting is DSR off if the DSR signal
is off.
The signals DTR, DSR, DCD, RTS, and CTS are reported on when the link detects them.
The transmitter or receiver is on while the link is actually transmitting or receiving data.
The transmitter is also reported as on if the link is attempting (unsuccessfully) to trans-
mit data on the line. This situation can occur if the transmit clock signal is not present.
3.4.2.5 Request Translation Table Report
Use the dlWrite function with the pOptArgs.usProtCommand field set to
DLI_PROT_GET_TRANS_TABLE to request any of the three translation tables. Use the MSB
of the
pOptArgs.usProtCircuitID field to specify the translation table to be read (1, 2,
or 3).
The dlRead translation table report response (the pOptArgs.usProtCommand field is set
to
DLI_PROT_GET_TRANS_TABLE by the DLI) has the same format as the dlWrite Set
Translation Table command (Section 3.4.1.1).
An unsuccessful translation table report request can return the following error code in
the
dlRead pOptArgs.iICPStatus field (see Appendix C for error handling):
DLI_ICP_ERR_BAD_PARMS
The parameter value(s) used for the function call are
illegal.
