Re: FreeBSD > 4.11 hardware issue with Asus PSCH-SR/SATA mobo

After replacing KimmoA with a small shell script on Tuesday 13 Jun 2006
00:56, the following appeared on stdout:

(yes, I cannot decide what to
call it!)

Its proper name, as has been said many times, is a null modem cable.
Another, later, MSese name for them is a laplink cable, although that
has been out of use for ages. However, there are three types, ignoring
the difference between hardware handshaking. For modern PCs, you need a
DB9F to DB9F null modem cable. It's called a null modem cable because
it connects two bits of DTE (data terminal equipment) together without
using the normal two bits of DCE (data communications equipment, in
other words a modem) between them, hence no modem or null modem.

Honestly, nobody is pulling your leg; humour is all well and good until
it starts inconveniencing someone. If you lived in the UK I'd make you
one and send it to you, but shipping to Scandinavia is probably more
than 2 DB9Fs, two hoods and a bit of cable is really worth.

Somehow, I strongly suspect that the output in the end of the cable
will be the same as on my screen.

It can't. Serial terminal emulators are just that: serial, displaying
one character at a time. It can't overwrite data already displayed
without clearing what it is overwriting. It simply displays raw ASCII
coming in over a serial line. A dumb terminal does exactly the same
thing [1]. PC graphics are a totally different idea.

Be sure to match the serial port settings on both ends, though. I
*think* the defaults are 9600:8N1 (9600 baud, 8 data bits, no parity,
one stop bit) after a quick glance at ttys on this box, but ICBW. The
handbook will be the authoritative source for this. You may also need
to hit the return key a few times to get the TTY to respond.

[1] Which reminds me, I have an old dumb terminal in the loft somewhere.
I must dig it out. I never thought it would be useful again - until
now.
