If you do not specify the ConnectRow/Connectcolumn/ConnectText value, this setting allows a "dumb but usually works OK" approach to ensuring a good connect.
"Dumb but usually works OK" means that as soon as possible, you should implement the Connect Text/Row/Column settings!
This value is used to count how much time has transpired since the last character/ transmission received from the host during an initial connection, in 1/10 second intervals.
The default for this setting is 20 (2 seconds of silence). If you just can't get around to implementing the Connect Text/row/column setting, and your connection appears to be "racing" with your script, increase this value until your script and your initial screen get it together.
