Try the following:
while your script is running type tail -f /var/adm/messages (assuming
your logging this info) this will tell you what your are connecting at.
Mine shows the following:
Dec 4 11:49:28 wallybox pppd[80]: pppd 2.1.2 started by root, uid 0
Dec 4 11:49:29 wallybox chat[81]: send (ATM^M)
Dec 4 11:49:29 wallybox chat[81]: expect (OK)
Dec 4 11:49:29 wallybox chat[81]: ATM^M^M
Dec 4 11:49:29 wallybox chat[81]: OK -- got it
Dec 4 11:49:29 wallybox chat[81]: send (ATDT1234567^M)
Dec 4 11:49:30 wallybox chat[81]: expect (CONNECT)
Dec 4 11:49:30 wallybox chat[81]: ^M
Dec 4 11:50:03 wallybox chat[81]: ATDT1234567^M^M
Dec 4 11:50:03 wallybox chat[81]: CONNECT -- got it
Dec 4 11:50:03 wallybox chat[81]: send (^M)
Dec 4 11:50:03 wallybox chat[81]: expect (ogin:)
Dec 4 11:50:03 wallybox chat[81]: 115200^M
If your connection is not at 115200 then try the following.
Try running these and then try your script again and see if you get any
further (or faster ;)
/bin/setserial /dev/cua1 spd_vhi
/bin/setserial -bag /dev/cua1
If your connection improves then put these in your dial script or in
/etc/rc.d/rc.local or something like that.
To recap (b/c of my lack of organization above)
1) start up your script
a) type tail -f /var/adm/messages (to monitor your login)
2) If you are not connecting at 115200 verify your serial port setting
a) /bin/setserial -bag /dev/cua1
mine shows:
/dev/cua1, Line 1, UART: 16550A, Port: 0x02f8, IRQ: 3
Baud_base: 115200, close_delay: 50, divisor: 0
Flags: spd_vhi skip_test
b) add /bin/setserial /dev/cua1 spd_vhi and to your script or something
or possibly your /etc/rc.c/rc.serial or rc.local file
c) check your baudrate setting in your dial script. Mine is set to 57600.
Hope this helps ;)
