Option–02 = This parameter defines the Channel A RTS/CTS delay or the
maximum allowable delay between the assertion of RTS and the
activation of CTS by the network modem. The value is specified in
milliseconds and ranges from 0 to 1,000 ms (0000 hex to 03E8 hex)
in increments of 1 ms and will default to 1,000 ms. This
parameter is only needed for RS–232–C/RS–423–A media
networks and will return the ERROR RESPONSE if specified for
Local Line media. The REPORT NETWORK MANAGER
CONFIGURATION command will return zero for the value of
this parameter for Local Line channels.
The default value of 1,000 ms was defined to allow operation with
a wide variety of modems, but cause the network operation to be
very slow. You can improve the performance of your network by
tuning the value of this parameter. Most typical modems will
work properly with a delay of 15 ms. You can start at this value
and either increment or decrement it until the circuit functions
properly.
Option–03 = The Channel B RTS/CTS delay, specified as described above.
