Can I assign a tty device number to a NIC card?

[gamesman]

we have to AIX boxes that send and receive information to TTY devices that are SA boxes. This limits me to 9600 baud. We're looking to increase throughput and I THINK we can use 10 mbps NIC cards and crossover cables labeled with the same TTY numbers as the SA boxes.

Does anyone know if this won't work, o rcan provide a better solution?

Thanks.

I think you can directly link network sockets or fd numbers with network interfaces and / or devices.
I hope it works...
Unix was made by and for smart people.

Thier alot of factor to look at.

1. are you running a rs600 box.
2. are you using dumb terminal or pc.

Now if you are on a rs6000 and are running pc here is what i would do.

make sure the rs6000 has a nic card 10 or 10/100
I would hook the risc box into a 10/100 16 port hub
then i would connect the pc into the hub ( make sure the pc have nic cards 10/100

I will work with you on this. there still other things you would need to do, let me know.
good luck

There's no PC involved. I have to rs6000's. One runs my patient data, admissions, billings, charges and such. The other runs my Lab systems. All my machine interfaces, test ordering resulting, reporting and such.

The hospital system send info to TTY 123 ( an sa box) which is wired to TTY 9 (another SA box) on the lab box where we read that information. We ack-ack each line for confirmation and we're transferring at 9600 baud. We want to speed up the transfer. We've increased baud rate before and have lost characters and the IBM rep has said that the TTY's over the SA boxes are pretty much limited to 9600.

So we're looking for a solution.

SA box are you talking about the black box that has tty ports on it and the from reads AC and thier are 16 ports in the back.
I want to make sure i know what you are talking about.

If it is try to raise the tty to 19200 dont go any higher
you will lose info.

 

[gamesman]

Yes. that's the SA box. We had an IBM rep in recently and he said that 9600 was pretty much the limit but we can try 19200.

Thanks.

Just get a cross-over cat-5 cable and connect it to the to NIC cards.

 

[gamesman]

bjverzal-- I don't have NIC cards in there yet. I'm asking the folks here, who I assume have a better UNIX understanding than myself if this will work in real life, since I THINK it works in concept.

 

[bjverzal]

I guess I got too caught up in the replies and forgot the original post.

You won't have too much luck putting a TTY on a NIC card. TTY's run RS-232 and NIC cards are either Ethernet, Token-Ring, ATM, etc... Just because the SA might have RJ RJ45 connector on it does not mean you can plug the NIC card into it.

Did 19200 work for you,
If it don't then maybe we can think of something else.
