My original question:

>I'm installing PPP-2.1.2 on a Sun 630mp running SunOS 4.1.3_U1 and
>once the connection is established, I cannot reach anywhere but
>the host (the 630mp) I connect using TCPMAN and run 'pppd crtscts
>silent proxyarp modem'. I have tried variations of the 'pppd' line,
>including all the switches I could think of (I printed the man
>page and dubugged all day today) with no luck.

Re-phrased: "I'm installing ppp-2.1.2 and I have no idea what's going on,
the list of errors is too long to comprehend, and I don't know which
question to ask first."

The "solution" is a bit too long and involved so...

The helpful hints I learned when installing ppp-2.1.2 on a 630mp running
SunOS 4.1.3_U1 - My testing was almost totally done using Trumpet Winsock
2.0b on a PC:

*this solved alot of problems!
>The SunOS versions up to their current shipment of 4.1.3_U1
>(as of 10/94) contain broken or ineffective code for supporting
>Request-to-Send (RTS) Clear-To-Send (CTS) modem flow control leads.
>The code was fixed by Sun in their patch #100513-04 (for 4.1.x)
>and #101621-02 (for 4.1.3_U1). (Rich Adamson)

2)Check gettytab for
  ^^ ^^^^^^^^^^ *when setting things up for 8 bit, hardware flow
control. No value and it defaults to 7 bit...

3)Make the following changes to modem settings
(examples given for USR Sportster 14.4K-configured for hardware flow control)
Q1- Quiet mode (no result codes)
V1- Verbal codes
&H1- Hardware flow control (CTS)
&I0- Software flow control disabled
&R2- Recieved Data to computer only on RTS
(BTW I later found out that disabling Data Compression increased transfer
rates a bit)

Special Thanks to: (Rich Adamson)
  If it wasn't for Rich Adamson, I never would have gotten any of
  this done before the 'deadline.'
  Thanks - ONE MORE TIME!

Additional Thanks go out to: (Perry Hutchison) (Operator) (Jon Lusky) (B.G. Mahesh)
