Hello,
I have diskless PCs that I connect to by serial port (using
null-modem cable). On the "master" PC I successfully use
cu or tip as follows:
cu -l /dev/cuaa0
or
tip sio0
----
I use to do this with FreeBSD 4.10 on my master PC. I recently
have upgraded to 5.3, and found a different behaviour of tip
and cu:
1. The bootup process over serial port used to be disconnected
with 4.10, before and after kernel loading (each time I had
to restart the cu command). With 5.3 this does not happen
anymore and the boot process over serial port continues
without any disconnections until the login prompt.
This is a very nice improvement indeed!
2. When a long command was executed over the serial port (for
example 'make buildworld'), I could disconnect by typing '~.`,
while the command itself would continue; at a later stage I could
get the command's output text by typing the cu or tip command
again. This was 4.10 behaviour.
However, with 5.3, when I type '~.', then cu/tip is disconnected
but also the running command is terminated. This is rather annoying.
Regards,
Rob.
