My question is why does my terminal session within
user-PPP seems to delay the display one character
previous to the current character typed. And, how do
I fix it where the current character will echo to the
terminal screen?
I start a manual user-PPP session by typing 'ppp' at
the shell prompt. PPP starts normal, displaying the
tun interface used. I type 'show physical', PPP has
set all the defaults correctly as specified under the
ppp.conf defaults: label. I start a terminal session
(typing 'term') within PPP (chat script under isp:
label always fails) and begin to enter the "at" modem
initialization strings. When I type the 'at' command,
I type 'a', nothing displays to screen. Type the 't',
and the 'a' echoes to the screen, hit ENTER and the
't' echoes. I have to press ENTER, to see that the
modem has returned the 'OK' response. To enter the
dial string I type atdt1234567, the same pattern as
described above occurs. After enter the last digit of
the phone and pressing ENTER the modem opens the line
and begins the connection. I must be sure an not
press ENTER while the modem(s) are executing the
hand-shaking process. After which, I press ENTER and
receive the 'CONNECT' response from the remote system
(actually not an ISP, but a Shiva LanRover switch).
The same pattern as before applies throughout the
login and password authorization. I am able to log on
to the remote system sucessfully, but not able to
start ppp on the remote system. I have tried minicom
and the same problem occurs. I have been able to get
a chat script (very odd, lots of //d 2-sec delays and
null expect strings) that will dial and connect to the
remote system; however, I still haven't been able
negotiate ppp. It is basically unusable.
Here are the specifics:
OS: FBSD 4.0 release (ship w/ The Complete FreeBSD
book)
SYSTEM: Gateway Solo2500 (laptop)
MODEM(PCCard): Xircom 10/100 + 56K Modem (XEM5600)
sio4 (serial port), cuaa4 (call-out port)
Thanks to all responses
