Hi all,

I am trying to use(access) single COM port into more than one java application to read incoming data on port.
Once one application started accessing port, other cant access it. Is possible to do so?

Anybody having any response for the same?

Thanks in advance.

I'm afraid not... when you assign a channel to a port it is allocated to you... gheeez never though I would miss old Cobol:
ASSIGN "COM1" TO INPUT-DEVICE REGARDLESS OFF LOCKS.

Do you realize the security breaches it would open if hundred processes can read from the same device ?
