Calling two scripts from batch file run asynchronously - batch-file

Question

I have batch file which gets user input, tranfers the input to a vb script.
set /p "whichPort= Which port do you want to reset:"
start /b "" cscript.exe //NoLogo loginInXyplex.vbs /portname:"%whichPort%"
Then a telnet session is exceuted from within the batch file, followed by the exection of the same script file in order to issue commands in the telnet session.
telnet.exe 192.120.187.35 2000
REM run the script
cscript loginInXyplex.vbs
When in the telnet session it appears the two scripts are running at the same time as the conmmands are out of synch so cannot log on properly
This is my first vb script so I could be missing somethong obivious, so i have included all source code :
Batch File:
#echo off
cls
echo.
echo Welcome to Xyplex Server Port Reset
echo.
pause
echo.
set /p whichXplex= Which Xyplex server is your device connected too: 1 or 2 ?
echo.
set /p "whichPort= Which port do you want to reset:"
echo Sending port "%whichPort%" to script file
echo.
pause
rem send using strat /b so we open script file on same command line window
start /b "" cscript.exe //NoLogo loginInXyplex.vbs /portname:"%whichPort%"
echo.
echo Conencting to Xyplex "%whichXplex%"
pause
if "%whichXyplex%" == "1" (
REM COnnecting to xyplex one IP:Socket
echo.
echo Connecting to Xpyplex %whichXyplex%...
telnet.exe 192.120.187.35 2000
REM run the script
cscript loginInXyplex.vbs
) ELSE (
rem ^ missing spaces in )ELSE(
echo Conencting to xyplex %whichXyplex%....
telnet.exe 193.120.187.245 2000
REM run the script in same widow wuth start /b
cscript loginInXyplex.vbs
)
Script:
set OBJECT=WScript.CreateObject("WScript.Shell")
OBJECT.SendKeys"{ENTER}"
OBJECT.SendKeys "access{ENTER}"
WScript.sleep 50
OBJECT.SendKeys "access{ENTER}"
OBJECT.SendKeys "SET PRIV{ENTER}"
OBJECT.SendKeys "system{ENTER}"
OBJECT.SendKeys "sh po all{ENTER}"
OBJECT.SendKeys "{ENTER}"
' source heer: http://stackoverflow.com/questions/21013428/pass-variable-from-batch-to-vbs
port = WScript.Arguments.Named.Item("portname")
OBJECT.SendKeys port
OBJECT.SendKeys "Port number selected is: " & port
OBJECT.SendKeys "{ENTER}"
OBJECT.SendKeys "Port reset....logging off...{ENTER}"
OBJECT.SendKeys "SET NOPRIV {ENTER}"
Wscript.Sleep 1000
OBJECT.SendKeys "Quit"
Any help appreciated.
