Serial ports of rx2600 / rp3440

Raj,

I'm trying to set up the basic serial connectivity.

For the tests, I just plugged in a terminal server's serial port accessed with KEA! via Telnet from a remote PC - this setup works when using it to connect to the console port.
The customer wants to connect an MGE Evolution UPS.

> Are the term bits 9600/N/none set?

I tried multiple things, setting the speed to 9600 and 19200, and even to 300 (as that is what stty tells me when queried about /dev/tty1p[24] )

Now I'm a bit confused - what do you want to connect? A UPS? A modem? Both?

Not yet. I'm testing by cat'ting a text file to the /dev/ttyX . Once I know the device, I intend to set up a getty on it.

Regarding the devices:

0/7/1/0 port 0 = "UPS port",
0/7/1/1 port 0 = "Console port",
0/7/1/1 port 2 = "Remote port"

My test environment consists of an rx2600. In this setup I'm trying to establish just the basic serial connectivity.

The customer's environment has an rp3440. He wants to connect an UPS (to be monitored by the OS).

In neither case, there are modems involved (which is why I didn't use the port labeled "modem" for my tests).

[Torsten. · Accepted solution]

The pathes above are for rp3440, here is for rx2600:

0/6/1/0 port 0 = "UPS port",
0/6/1/1 port 0 = "Console port",
0/6/1/1 port 2 = "Remote port"

Okay, replacing the descriptions with some facts :-)

Here's the output of the MP's CA and SA commands, and of HP-UX' ioscan -fun

Which devices do you think are associated with the serial ports?

[Martin Vorlaender]

Thanks, Tosten, got it. 0/6/1/0 or /dev/tty0p0 is the right one.

I think I got confused by the many devices listed with 0/6/1/1...

Okay, so now I have got a device. But setting it up seems to be another problem (see attachment).

I apologize if these seem like stupid questions - I'm just getting into HP-UX; I'm a VMS guy...
