Shell Programming and Scripting

Hello all..

I need to script SLIP dial-up connections and wanted ask others about the following;

- does pppd support SLIP (noticed some releases do and some don't)
- if pppd doesn't support SLIP can bash variables be passed to a dip script (e.g. phone-number, ip-address)
- or is another means of establishing a SLIP connection

I have PPP dial-up connections working and was curious if anyone has ran into the following problem;

- each PPP connection established has a unique unit id (e.g. ppp0, ppp1 - basically the device numbers/indexes, in my case, are unique)
- from time to time chat timeout errors occur when initiating more than one PPP connection simultaneously (e.g. ppp0 on tty00, ppp1 on tty01, ppp2 on tty02)

Please advise if additional information is needed and I am using Ubuntu.

Thanks in advance.
