Our system has the following equipment:
1 device with 1 serial connection (RS422)
1 PC with a VB6 program that was initially designed to hook up directly to the RS422 device.
1 Pc with a different VB6 program that was initially designed to hook up to the RS422 device.
1 Ethernet to Serial black box.
2 Serial to Ethernet diverter programsm, one in each PC.
What we need to do is allow both PC's to communicate with the RS422 device at the same time. The problem is that when one PC has the port open, the other PC can't talk to it. If we design one of the PC programs to not open the port, just listen, that might work, but when we wanted to use that program only, we wouldn't open the port.
Is there any way to allow both PC's access to the single RS422 port on the devicce?
