5.4.1 Commands using Raw dlWrite

Section 5.4.1.1 through Section 5.4.1.15 explain how to issue specific commands to the

BSC 2780/3780 software using the

dlWrite function. Call dlRead to receive the command

confirmation response (the

dlRead pOptArgs.usProtCommand field is set by the DLI).

5.4.1.1 Set Translation Table Command

Use the dlWrite function with the pOptArgs.usProtCommand field set to

DLI_PROT_SET_TRANS_TABLE to set translation table 1 or 2. Use the MSB of the

pOptArgs.usProtCircuitID field to specify the translation table to be set (1 or 2). Each link

can use either of the two tables for character translation. After Freeway startup, the

tables contain the default values shown in Appendix C. Use the data area of the buffer

pointed to by the

pBuf parameter to send the translation table values. The first 256 bytes

of data are the conversion values for the ASCII-to-new character set translation. The

next 256 bytes are the conversion values for the new character set-to-ASCII translation.

An unsuccessful Set Translation Table command can return one of the following error

codes in the

dlRead pOptArgs.iICPStatus field (see Appendix D for error handling):

DLI_ICP_ERR_BAD_MODE

The function request is not available for the requested

access mode.

DLI_ICP_ERR_BAD_PARMS

The parameter value(s) used for the function call are

illegal.

5.4.1.2 Clear Statistics Command

Use the dlWrite function with the pOptArgs.usProtCommand field set to

DLI_PROT_CLR_STATISTICS to clear the link statistics report. The link statistics are cleared as

soon as this command is received. The statistics are automatically cleared when a Start

Link command (Section 5.4.1.5) is issued.
