serial port communication

Dear all,
I'm trying to communicate with my E4401B through the serial port. In the agilent Connection Expert (I have attached the snapshot below) the port connection is shown. But I'm not able to send any commands through the interactive IO (except for *IDN?). I always get a timeout error, why is it occurring?. Help please.
I get the following message in Interactive IO:

* Connected to: ASRL1::INSTR
-> *IDN?
<- Hewlett-Packard, E4401B, MY41440384, A.10.00
-> *CLS
! VI_ERROR_TMO: A timeout occurred
Visa ErrorCode: 0xBFFF0015 (-1073807339)

Regards,
Lokesh.
