A transmission delay can be set in the PC Setup to create a minimum interval
between sending a response from the PC to a Host Link command until the be-
ginning of sending the response to the next command.
The delay is not used in the response to the first command. The delay will affect
responses to other commands only if the normal time for the response comes
before the time set for the transmission delay has expired.
If the delay time has already expired when the next command is received, the
response will be spent immediately. If the delay time has not expired, the re-
sponse will be delayed until the time set for the transmission delay has expired.
The operation of the transmission delay for responses to host commands is illus-
trated below.

The transmission delay will also be effective in PC-initiated communications as
a minimum interval between sending commands to the host.
The delay is not used in sending the first command. The delay will affect other
commands only if the time set for the transmission delay has not expired when
the next command is ready to be sent.
If the delay time has already expired when the next command is ready, the com-
mand will be spent immediately. If the delay time has not expired, the command
will be delayed until the time set for the transmission delay has expired.
