Note for run-time error 105h
Socket close processing (SOCKET.FN3, Function #28) following occurrence of run-time error
105h would not complete immediately. This is because a FIN packet will be transmitted repeat-
edly in the socket close processing until the communications device receives any response
from the server independent of the power on/off state of the communications device.
The socket close processing period may be shortened by changing the retry count that deter-
mines the number of FIN packet retransmission times and is controlled by
SOCKET.FN3,
function #24, option #26.
(Example)
Sock.Err: ’Socket error-handling routine
print "ERR:";hex$(err.code%) ’Display error code
print "ERL:";hex$(err.line%) ’Display error line number
if sock.stts%>=3 then ’If OK until socket generation,
optname%=26 ’set retry count
option=0 ’No retry (transmit once)
call "socket.fn3" .fcSSckOpt sockfd%,optname%,option
call "socket.fn3" .fcClose sockfd% ’Close socket
end if
if sock.stts%>=2 then ’If OK until connection of TCP/IP
’communications pathway,
call "socket.fn3" .fcTDiscnn interface% ’Disconnect the pathway
end if
if sock.stts%>=1 then ’If OK until opening the spread
’spectrum communications device,
close #hCom3% ’close the device
end if
goto main ’To main program
