* FUNCTION: cqd_RWTimeout
|
||
*
|
||
* PURPOSE: Process a TIMEOUT error while reading/writing/verifying. If
|
||
* the FDC does not report any status within the amount of time
|
||
* that the tape would pass apporximately 4 segments, it must
|
||
* be assumed that there is no data on the tape.
|
||
*
|
||
* HISTORY:
|
||
* $Log: J:\se.vcs\driver\q117cd\src\0x11035.c $
|
||
*
|
||
* Rev 1.3 12 Jan 1994 17:05:58 KEVINKES

|
||
*
|
||
* Rev 1.2 02 Dec 1993 14:51:10 KEVINKES
|
||
* Modified to update the crc list instead of the bsm.
|
||
*
|
||
* Rev 1.1 11 Nov 1993 15:20:36 KEVINKES
|
||
* Changed calls to cqd_inp and cqd_outp to kdi_ReadPort and kdi_WritePort.
|
||
* Modified the parameters to these calls. Changed FDC commands to be
|
||
* defines.
