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

repeatedly 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

determines the number of FIN packet retransmission times and is controlled by SOCKET.FN3,

function #24, option #26.

(Example)

Sock.Err: 'Socket error-handling routine

'processing

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" 24 sockfd%,optname%,option

call "socket.fn3" 28 sockfd% 'Close socket

end if

if sock.stts%>=2 then 'If OK until connection of TCP/IP

'communications pathway,

call "socket.fn3" 43 interface% 'Disconnect the pathway

end if

if sock.stts%>=1 then 'If OK until opening the spread

'spectrum communications device,

close #hCom% 'close the device

end if

goto main 'To main program
