PCOMM not working in vbscript

[moving]

Now PCOMM not working in vbscript. Does anyone know of any problems running PCOMM classes in vbscript to conncet with AS400. The following works on some computers (sends"123" to the AS400), but not others.

Dim autECLPSObj

Set autECLPSObj = WScript.CreateObject("PCOMM.autECLPS")

Dim autECLConnList

Set autECLConnList = WScript.CreateObject("PCOMM.autECLConnList")

autECLConnList.Refresh

autECLPSObj.SetConnectionByHandle (autECLConnList(1).Handle)

autECLPSObj.SendKeys "123"

set autECLPSObj = nothing

set autECLConnList = nothing

Thank you.
