MULTIPORT SPOOLER VIII (4-, 8-, and 12-Port Models)
/T
set Timeout delay
Use this command to define the length (1 to 999 seconds) of the timeout.
A timeout is used to indicate when the end of a task has been reached.
End-of-task identification is important for two reasons:
• At the end of each task (when the timeout expires), new commands may
be sent to the Multiport Spooler VIII.
• When a task is being transferred to a peripheral, no one else can use the
peripheral until the sending port’s timeout expires. Therefore you must
set an adequate timeout before transmitting a task.
When some application programs transmit data, they do so more or less
continuously. Printing from a word-processing package is a good example.
For this type of application, we recommend that you set the timeout to
6 seconds. By contrast, complex graphics-software packages such as AutoCAD
perform many calculations as they print or plot, which causes temporary
pauses in data transmission even though the task is still active. If you expect
transmission delays, set the timeout to 20 to 30 seconds. If the timeout is too
short, the Multiport Spooler VIII concludes (when the timeout expires) that
the task was finished and goes on to the next one prematurely.
Format
@@/Tn@
n
The length of the timeout in seconds (1 to 999).
Example
@@/T25@
Sets the timeout to 25 seconds for the current port.
NOTES
A port’s LED stops flashing when the port’s timeout expires.
The timeout must expire before another command may be
transmitted. The UCTP’s Break feature automatically cancels the timeout
before each command, making it easier to send a series of commands.
