modem to modem connection-linux to mac
|
|
|
| I have a REAL old linux box(200Mhz.) and a REAL old Mac Classic. I want to
hook up the mac to be sort of a dumb terminal to the linux comp. I have the
terminal software, etc. set up on the mac, but I don't know how to set up a
modem on Linux, and how to run (getty? Idon't know what I should run) accros
the modem line.
Is this configuration even possible? you may email me at
macman552NO@SPAMhotmail
.com, or post via this group.
--macman

Yes, but use a null-modem serial cable, not two modems. Modems require the
intervention of a telephone company.
A null-modem serial cable (Radio Shack and elsewhere) allows you to
interconnect two machines that have serial-aware terminal programs.
To make the Linux box listen for logons on the first serial port, add this
to /etc/inittab:
# Allow serial port logons
S0:12345:respawn:/sbin/agetty ttyS0 19200 vt100
As to the Mac end of the cable, well, you're on your own.

I thought most (if not all) modems had some way of connecting without
using the exchange (a sort of "leased line" mode).

hmm, should it realy run in runlevel 1?

just as a guess
8a:345:respawn:/bin/cat > /dev/tty8 < /dev/ttyS0
8b:345:respawn:/bin/cat < /dev/tty8 > /dev/ttyS0
I think cu may also deserve look.

I am sure you can think of the reason why -- in the event of a keyboard
failure or display problem in an otherwise valid, running system that needs
to be shut down cleanly.

Not for interactive serial transactions such as telnet.
