set in BIOS.
5 Click Apply to save the settings.
6 Click Advanced Settings . The Serial Over LAN Configuration Advanced
Settings
screen is displayed that allows you to adjust the SOL
performance. See Table 9-1.
NOTE: If you change these values to lower values, the Virtual Console feature of
SOL may experience a reduction in performance. Furthermore, the SOL session
must wait to receive an acknowledgement for each packet before sending the next
packet. As a result, the performance is significantly reduced.

Setting Description
Character
Accumulate
Interval
The typical amount of time iDRAC6 waits before sending a partial
SOL data packet. This parameter is specified in milliseconds. It is
recommended to use 10 milliseconds for optimal performance.
Character Send
Threshold
Specifies the number of characters per SOL data packet. As soon
as the number of characters accepted by iDRAC6 is equal to or
greater than the Character Send Threshold value, iDRAC6 starts
transmitting SOL data packets that contain numbers of characters
equal to or less than the Character Send Threshold value. If a
packet contains fewer characters than this value, it is defined to be
a partial SOL data packet.
It is recommended to use 255 characters for optimal performance.
