NEC 2000 IPS not receiving SMDR

[pembajak]

Hello,

I wrote an application to receive a data using serial port on the PC, it has been working fine with various PBX system and hyperterminal.

However my application doesn't receive the SMDR from NEC 2000 IPS even though when i am using NEC 2000 IPS with hyperterminal it works fine.

I am not quite sure what is the different between hyperterminal and my application. At the moment my guess is there must be some sort of handshake between hyperterminal and NEC 2000 IPS.

Any information regarding this would be much appreciated.
Thanks.

Are you saying that you can see data coming out with hyperterminal but using the same port and leads you can't with your programme?

What language are you using?

I could possibly show you some very rough programming in VBA that works. It may give you some clues. I also have a VB 2005 programme that works (pretty rough programming though).
