| Two things that come to mind:
1) Trumpet Winsock is currently at V3.something. You might try
upgrading to at least V2.1f.
2) You mentioned that your server changed. You didn't mention whether
your modem has changed, whether the server's modem has changed, or
the initialization commands you're sending to your modem or to
your server in your login.cmd. For example, your new server might
be giving you higher speed connections that your old port speed and
flow control settings are not handling properly. Or your new server
may be using XON/XOFF flow control but your server initialization
commands are not guarding XON/XOFF characters in the data stream.
There are any number of possibilities involving speed and flow
control that you would be less likely to see in an interactive
terminal emulation activity than in a data-stream-oriented PPP
session, and if they are different servers, you have essentially
no data on whether your modem and port are properly configured for
the PPP server.

| I too am having similar problems - could make somewhat tempermental
Trumpet/PPP connections in the past but now can get nothing into PKO.
This is with both with a registered version of 3.0d and an earlier
2.0b? version. At present I can dial in, give the password and then
things die with a "PPP[C021] state = stopped" note in the log after
about ten "PPP[C021] SND CONFREQ ..." messages.
Any thoughts as to how to track the problem down would be most
appreciated. Since it appears to be important to have the settings
correct to interact with the server, I was wondering if there is any
way to query a particular server to see what it's expecting.

| re: .-1
There's no way I know of to query the modem on the other end, which
sounds like your most likely problem. For that, you just have to
carefully examine your own modem and port settings. Despite the phrase
"Hayes compatible", modem command sets vary quite a bit. Of the 2
modems I've had the pleasure to work with using PPP, the appropriate
initialization strings (@port-speed) have been:
DEC DF296@19200: AT&FM0X5%F2%M1&C1&D2&S1$D5$K1$M2S23=60S7=60
USR Sportster 33600 FAX modem@115200: AT&F1M0&S1S7=60
always using RTS/CTS (hardware) flow control.
If the server is a recent version of a DECserver 700 with dynamic
address assignments, I use the following, which may be overkill, but
works:
Local> set port ppp lcp passive enable
Local> set port ppp lcp acfc enable
Local> set port ppp lcp mtu 256 <- a better choice might be
Local> set port ppp lcp mru 256 296 with matching Trumpet
Local> set port ppp lcp pfc enable settings and MSS=MTU-40
Local> set port ppp lcp map 0 <- this server uses RTS/CTS.
Local> set port ppp lcp enable for XON/XOFF, use "A0000"
Local> set port ppp ipcp compression enable [these are NOT for your port]
Local> set port ppp ipcp address enable <- dynamic addresses
Local> set port ppp ipcp enable
Local> set port ppp ipxcp enable
Local> set port ppp atcp enable
Local> c ppp
"Local> help set port ppp" will let you see the options.
I think "show port ppp" will show you the default settings.

| Thanks for the ideas - it isn't the modem settings because with the
SAME modem settings I can access other things OK (even the dumb tty
port that Trumpet gives me works Ok for anything that I can do that
doesn't require a VT100 or better).
Newer versions of Trumpet have EXACTLY the same symptoms (I tried at
the weekend). I don't have access to the PPP server I connect to - I
believe it is an Ultrix system.

Be careful with that assumption. If you have speed, flow control, or
buffering problems because of inappropriate modem or port settings, it
might work perfectly well with something as undemanding as slow human
keystrokes and short text responses containing only printable
characters, but choke when you try to push a big hunk of (binary) data
through it. Can you, for example, do anything like a high-speed ZMODEM
or KERMIT from the _same_ server? If you could post some actual
information about your modem, port settings, modem initialization
string, Trumpet setup parameters, and the commands you're sending in
your Trumpet login.cmd, that might help.

Then that eliminates the Trumpet software as the problem. I would then
look more closely at your modem and port configuration and at your
Trumpet configuration. It could still be something having to do with
the server initialization (either in your login.cmd or at the other
end), but without knowing anything about what the server is or what
you're saying to it, I don't have any specific suggestions there. Does
the server display an identification banner when you connect to it? A
copy of the contents of your Trumpet login window showing the
connection dialog might help.

| Tom, thanks for the suggestions.
I'm still not having any luck on getting a Trumpet PPP connection to
work here at PKO. This particular setup is to a Hayes Optimus 28.8
modem connected to a DECserver 700. I've tried making connections with
my home WFWG 3.11 (with Win32S extensions) system using an Intel 14.4
faxmodem and through a laptop with a Megahertz 28.8 card. In both
cases I have my own IP address and do a manual dialin with only a PAP
password dialog. No scripts are used for login. Apparently there is a
direct connection to the server since no "Local>" prompts are
available to do any "set ports" or whatever.
Not many users are connecting here via Trumpet - I guess many problems
in the past have encouraged most people to go to a RAS connection.
But I'd prefer not to have to "upgrade" to W95 or NT at this point to
get the RAS capability. So Trumpet seems to be my only option.
I suspect that the problems I'm having have to do with the proper setup
of the DECserver and it's modem. Unfortunately, on-site support for
the Trumpet connection does not have a high priority here. Does anyone
have a working setup who might be able to supply us with settings and
whatever that will work? Also, is there anyway I can try my laptop on
someone elses site to verify at least that my Trumpet software works?
Following is a session log from the laptop with everything but the
comm messages logged. I've added some comments as to what's going on
in brackets. Any suggestions would be welcome.

| re: .7
You're sure this isn't a RAS-only server, right?
I can't tell what all the modem settings mean, but one thing I do see
is that you have a fixed port speed of 38400 but you have a connect
speed of 28800 with compression enabled. That means that data will be
incoming to you through a pipe that is up to 4 X 28800 = 115200 wide
and trying to fit through at 38400 straw. Change your port speed to
115200 and make sure that you have RTS/CTS flow control enabled on both
your port and your modem. That's probably not the only thing, or even the
main thing, but it will eventually cause problems.
I'm a little confused by the order of events (that's nothing new), but
the trouble may start with that "internal error" immediately after
you hit "Manual login". After you connect and hit <ESC>, Trumpet seems
to be repeatedly requesting an LCP PFC and ACFC configuration and
getting no response, finally giving up. Instead of hitting <ESC> after
the "CONNECT 38400", have you ever tried hitting <CR> once or twice?
