TIME OUT
The TIME OUT command sets the number of seconds that the Micro488/EX will
wait for an IEEE bus transfer before declaring a time out error. The Micro488/EX
checks for time out errors on every byte (including command bytes as a controller) it
transfers.
Time out checking may be suppressed by specifying time out after zero seconds.
The default time out is 0 seconds, or time out disabled.
SYNTAX TIME OUT[;][n]

TI[;][n]

zero or unspecified, ignore time outs.
