The symptoms:
I dial in to the PortMaster at 2400bps.
If I remain on the line I get a login prompt and can log in
as a regular user with no problems.
Supposedly the portmaster auto-detects PPP. So:
If, after dialing and connecting I run pppd on that line
it sends a few LCP ConfReq PPP packets. At about the time
the login prompt would normally appear without PPP the
portmaster starts responding to the packets, but not with PPP.
Instead of nice [7E FF ... 7E] bracketed packets it sends [CF 44 ...]
packets.
Eventually the pppd gives up and closes the connection, since it's not
seen any PPP responses.
Going:
set console
set debug 0x51
to debug PPP transactions per the manual generates a ringing silence,
so I assume the PortMaster doesn't think it's seeing PPP.
The other debug codes seem undocumented, and 0xff or 0xffff produce
nothing relevant or huge waterfalls of stuff, respectively. Argh.
I have run PPP looped back into the Sun with two pppds, and across the
room to a Mac with PPP without any problems. This and the weird data
the PortMaster sends lead me to suspect a configuration problem with
the portmaster.
The setup:
The data rate is 2400bps, 8 data bits, 1 stop bit, no parity.
A Sun SPARC IPC running SunOS 4.1.3 with ppp-2.1.2 installed.
The PortMaster says:
Livingston Enterprises PortMaster Version 3.3.1c1
I have run out of ideas for further tracing of the problem.
Does anyone recognise the PortMaster's response
Any help would be appreciated,
