cmtrak -- HBA driver for Colorado Memory Trakker 120 and Trakker 250 tape drives

Description

Trakker 120 and Trakker 250 are two tape drives from Colorado Memory Inc. These drives support the QIC-40 and QIC-80 standards respectively. Normally, a cartridge formatted in one drive cannot be used with the other type, but a QIC-80 drive can read data from a tape formatted in a QIC-40 drive. The driver follows the mfpd protocol to use the parallel ports.

ioctl calls

The driver supports the following ioctl(2) command:

SDI_SEND
Send a SCSI command to the drive. Using SS_WRITE to write data requires a SS_FLMRK (write a filemark) command to be sent at the end to flush any remaining buffered data to the tape.

Unsupported SCSI commands are:


SS_SDDGN
Send diagnostic.

SS_LOCK
Prevent or allow media removal.

SS_TRKSEL
Track select.

SS_SPACE
Skip over filemarks only.

B_GETTYPE
Return bus_name as port and drv_name as cmtrak in the bus_type structure.

HA_VER
Return version number of the HBA in the structure ver_no.

The SDI_BRESET ioctl is not supported because there is no SCSI bus.
