PPPD on ttya with serial console...?

Hi. I am very very new to Solaris. I found an abandoned Sun Blade 150. I created a 3-wire null modem cable, connected it to an abandoned laptop and successfully installed Solaris 10 using the serial port. This laptop doesn't have ethernet. So I want to establish a PPP connection.

Part of the problem is Windows 2000 as the client I'm sure, but I tried a simple test along the lines of:

pppd /dev/ttya 9600 192.168.1.2:192.168.1.3 local nocrtscts noauth connect "chat 'CLIENT CLIENTSERVER\c'"

Promptly after issuing the command a shell prompt "#" is shown again, but 'chat' seems to have control. After starting Windows 2000's "Direct Connection" (and it fails), returning to the terminal eventually shows "LENLETCINLE: not found" such that probably it is sending "CLIENT" a few times and it eventually gets there to the shell after chat times out..

I think the issue is that /dev/console is also on the serial port.. It's currently the only way I can access the machine so I don't really want to replace it. Also, it's a 3-wire serial cable, but at 9600 baud I don't think flow control would be the issue. We're low on pins and I didn't want to waste them for my games. heh. I have changed the modem settings on the Windows 2000 client to 9600 no flow as well.

Any pointers on how to proceed? Smilie

hm, I had very similar problem trying to get Amiga online through Windows. this helped me: Connecting a Palm Vx to Windows XP with PPP.
don't you have any other serial port available?
edit: perhaps you could make a script that runs that ppp connection and set it to run in future. then disconnect terminal and wait for script. and when its connected use ssh?

I think I recall using this for an Apple Classic II. Smilie

I suppose since neither machine is networked, using Windows as the server is just as good. The other part changes the CLIENT CLIENTSERVER strings to normal ppp strings, though that should be taken care of with 'chat'.

I may give it a go anyway. I will probably just bring in my personal netbook tomorrow (to connect via ethernet).

I see no other serial port available.

Thanks.

Having more success. I misused single quotes in my chat script, and pppd wasn't reading ttya because it was already open. Using something like,

exec pppd file test.ppp

fixes most things but the terminal seems to be put back in cooked mode since I must hit enter after 'CLIENT' to get the 'CLIENTSERVER' response..

Almost...

I made link over ttya without messing with any services basically just logged in as root on serial console and type

exec pppd /dev/ttya 9600 192.168.1.2:192.168.1.3 nocrtscts local connect "sleep 20; echo CLIENTSERVER"

That was good enough. Maybe someone else crazy as me will be helped with this. Helps to have a couple ssh sessions verus a single serial console. Now to actually learn this stuff! Smilie
