How to connects to Linux machine via null-modem cable and cu command?

[Sun Zongjun-E5739C]

Hi, Koshy

Thanks for your timely reply. It is my fault configuration on the linux machine. 

I use linux instead of vt100 (vt102). 
S1:23:respawn: /sbin/agetty -L ttyS0 115200, 9600 linux

Windows can work with this configuration, but cu and FreeBSD can't.

I replaced it with vt100
S1:23:respawn:/sbin/agetty -L ttyS0 115200, 9600 vt100

That is OK.


Thanks a lot


Best Regards
Sun Zongjun

What happens when you hit 'Enter' a few times?

One thing you could check is the expected baud-rate/parity/stop-bit settings at the server.
