Bob Armstrong sez...
I want a little gizmo with an RS-232/DB25 on one side and a RJ45/10baseT
on the other. It should speak TCP/IP, specifically telnet, and convert it
to RS-232. Kind of like a print server, except for telnet/RS232 instead of
lpd/Centronics.
The idea is to use it to put some of my old computers on the network
by plugging it into their console serial ports.
There are enough microprocessors around today with embedded TCP/IP
stacks that such a thing would not be that hard to build, but it
sounds like the kind of thing that somebody else must have already
done.
Can anybody give me any pointers to such a gizmo?
It's called a "terminal server" and many of these things exist.
They generally have lots of serial ports; 8, 16, 24, and up.
You might even be able to find one on ePay...
Cheers,
