I'm trying to access an rx2600 using a serial connection (or really, a customer's rp3440; both machines have the multiplexed DB25 connector on the MP board). I do have console access through the console RS232 port, but I'd like to be able to connect through another terminal connected to the remote modem or general purpose port.
An ioscan -fun suggests the devices are /dev/tty1p0 (console), /dev/tty1p2, and /dev/tty1p4, but I've been unable to connect though any of them, or even set the serial characteristics through stty...
What am I missing?
Solved! Go to Solution.

Re: Serial ports of rx2600 / rp3440
thanks for the suggestion.
To avoid additional problems caused by some modem control signals incorrectly set, until now I played with the third serial port (labeled "UPS", and described as "general purpose" in the quick specs).
Just did a quick test with the terminal connected to the remote serial port (setting it to the 19200 bps suggested by the MP's CA display) - no success.

Martin

Re: Serial ports of rx2600 / rp3440
I can't believe that you have to buy one of those (8 port, at least) MUX PCI cards to connect a simple serial device...

and

the modem (connected to the MODEM connector) is either under MPs full control or can be used by the OS too (i guess this is what you want to do).
Refer to
MP:CM> help sa
MP:CM> help ca
Hope this helps!
