Hello, may I see your chat script?
Here is the line I use to start pppd:
 pppd /dev/tty02 115200 crtscts defaultroute connect /root/uacn.sh
Here is the contents of /root/uacn.sh:
 #!/bin/sh
 rc=4
 while [ $rc != 0 ]; do
 chat -v -f /root/uacn.txt
 rc=$?
 done
 exit 0
That file runs keeps running my chat script until
it gives a return code of 0, which means success.
Here is the contents of /root/uacn.txt (annotated):
 ABORT BUSY			<-- quit if busy dial tone
 ABORT "NO CARRIER"		<-- quit if no dial tone
 "" ATZ			<-- reset modem
 OK AT&F&C1&D2M		<-- set to factory default, plus some xtra
 OK ATDT4740771		<-- dial my ISP (my work/university)
 CONNECT \r			<-- send [RETURN] after connecting
 name> foobar			<-- "Username>" prompt and my (not my real) username
 word> spanky			<-- "Password>" prompt and (not my real) password
 > c\sppp			<-- varying prompt always ends with ">"
 				 and "c ppp" ("\s" means [SPACE]) connects
I hope the email server doesn't wrap these lines and
mess up the text...
Hope this helps (please post your scripts for
more specific help),
