This ruby code handles the reconnection feature
```
# Handy method to ensure that a connection is established and active.
#
# The connection is resetted on the IB-side at least once a day. Then the
# IB-Ruby-Connection has to be reestablished, too.
#
# check_connection reconnects if necessary and returns false if the connection is lost.
#
# It delays the process by 6 ms (150 MBit Cable connection)
#
#? a =? Time.now; G.check_connection; b= Time.now ;b-a
#?? => 0.00066005
#
?? ?def check_connection
?? ???? ??? ??? answer = nil; count=0
?? ???? ??? ??? z= tws.subscribe( :CurrentTime ) { answer = true }
?? ???? ??? ??? while (answer.nil?)
?? ???? ??? ??? ??? begin
?? ???? ??? ??? ??? ??? tws.send_message(:RequestCurrentTime)??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? ??? # 10 ms? ##
?? ???? ??? ??? ??? ??? i=0; loop{ break if answer || i > 40; i+=1; sleep 0.0001}
?? ???? ??? ??? ??? rescue IOError, Errno::ECONNREFUSED?? # connection lost
?? ???? ??? ??? ??? ??? count = 6
?? ???? ??? ??? ??? rescue IB::Error # not connected
?? ???? ??? ??? ??? ??? reconnect
?? ???? ??? ??? ??? ??? count +=1
?? ???? ??? ??? ??? ??? sleep 1
?? ???? ??? ??? ??? ??? retry if count <= 5
?? ???? ??? ??? ??? end
?? ???? ??? ??? ??? count +=1
?? ???? ??? ??? ??? break if count > 5
?? ???? ??? ??? end
?? ???? ??? ??? tws.unsubscribe z
?? ???? ??? count < 5? && answer #? return value
?? ?end
