Hi,
I'm trying to get linux to talk to a Cisco 837 using the supplied blue console cable. The serial port is detected by linux and seems alright as you can see below.
/proc/tty/driver/serial
0: uart:16550A port:000003F8 irq:4 tx:149 rx:121Tx and Rx indicate that bytes are being sent/received. Now here's the thing, neither minicom nor kermit will show any output at all (i'm no guru when it comes to this but i have my settings correct as in speed, parity, stop bits etc..)
Also, the cisco shows this:
------------------------- eon#show line console 0 Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns Int 0 CTY - - - - - 0 163 0/0 -
Line 0, Location: "", Type: "" Length: 24 lines, Width: 80 columns Baud rate (TX/RX) is 9600/9600, no parity, 2 stopbits, 8 databits Status: Ready Capabilities: none Modem state: Ready Special Chars: Escape Hold Stop Start Disconnect Activation ^^x none - - none Timeouts: Idle EXEC Idle Session Modem Answer Session Dispatch 00:10:00 never none not set Idle Session Disconnect Warning never Login-sequence User Response 00:00:30 Autoselect Initial Wait not set Modem type is unknown. Session limit is not set. Time since activation: never Editing is enabled. History is enabled, history size is 20. DNS resolution in show commands is enabled Full user help is disabled Allowed input transports are none. Allowed output transports are telnet ssh. Preferred transport is telnet. No output characters are padded No special data dispatching characters
-------------------------
Notice the 'noise' column, and that value of 163 since that's what happens when i connect using minicom and type random stuff. Though I don't get replies, that increases the noise count, so it must be that the Cisco is discarding the packets as noise.
Does anybody know how to solve this and get it to work?
Cheers.
