Subject: multiple devices on an RS232 connection

Hi,

I am looking for a way to connect up to 10 RS232 devices to a single RS 232 port on a PC at one time and be able to gather data from each device
sequentially.

My thinking is to clock a 4017 (one of ten decoder) or similar chip with the DTR line and have it enable the first device, clock it again to enable the second device, etc.

This solution will likely require converting from rs232 to ttl (or similar) to RS422 and back to RS232. Pretty messy!!

Any other ideas?

If you need further details contact me.

Thanks
Jim
