•
To record data, select File SCSI Tape Record Data → → . All data
subsequently received by Scream! will be recorded onto the
tape, regardless of where it comes from, or whether the Rec.
option is set for the streams. Choose File SCSI Tape
→ →
Record Data again to stop recording.
If the tape drive fails or goes offline for any reason, Scream! will
begin buffering data internally, and will continue recording
once the fault has been resolved.
•
To replay data, select File SCSI Tape Replay Data → → . This
opens a Replay window for loading the data on the tape into
Scream!. Data are loaded into Scream! one block at a time;
Scream! then waits until a time determined by the Faster and
Slower icons in the Replay window before loading the next
block. Setting these icons to Max stops Scream! from waiting at
all. If you are using a slow tape drive, Scream! may not need to
wait, and so the faster replay speeds will be equivalent.
Do not attempt to replay data from the tape whilst you are
recording to it.
•
To rewind the tape to the beginning, select File SCSI Tape → →
Rewind. If you are recording data onto the tape, Scream! will
resume recording as soon as the rewind operation finishes.
•
To eject the tape, select File SCSI Tape Eject → → , or press the
Eject button on the tape device. If you are recording data onto
the tape, Scream! will begin buffering data internally until the
tape drive is ready to accept new data, and will automatically
resume recording on the new tape. This feature allows you to
“hot-swap” tapes directly, without losing any data.
If no compatible tape drives are detected, these menu options will be
greyed out.
9.4 Automatic playback
If a directory called autoload is present in Scream!'s program
directory, Scream! will automatically look in it for GCF data and play
it into the stream buffer in real time, as if it came from a local serial
port. The data appear under Autoload in the Files section of Scream!'s
stream list.
This feature allows you to transfer real-time data to Scream! by merely
placing files in the designated directory. For example:
