The following advanced communications options can be configured:
Flow Control
Select None for no flow control.
Select Software for XON/XOFF flow control.
Select Hardware for RTS/CTS flow control.
The default value is Hardware flow control.
Debug Level
The default value is 0 (no debugging).
Level 1 debugging logs negotiation information as the link
is established and removed.
Level 2 debugging logs all negotiation plus all PPP
packets in hexadecimal format.
WARNING:
Level 2 debugging causes the logfile to grow exceptionally
quickly. If you configure level 2 debugging, bring the link
down once you have enough log data, then reset the log level
to 1 or 0.
Set to the name of a packet filter entry in /etc/pppfilter.
See
packetfilter(SFF)
for a description of the format of this file.
Remote Site Uses SCO TCP/IP 1.2.0
Set to Yes if the remote site uses SCO TCP/IP Release 1.2.0.
Proxy ARP entry
Set to Yes to force PPP to make proxy ARP
entries for local and remote IP addresses into the
ARP table. For more information, see
``Proxy ARP''.
On-card framing
This option controls the use of on-card framing by smart
asynchronous serial port devices on a per-endpoint basis.
If set to Yes, PPP framing is performed by
the asyh STREAMS module in the PPP stack.
If set to No, PPP will attempt to configure
the smart serial card hardware to perform framing.

ppphosts(SFF).
