Re: HELP URGENT - Do I need I-STAR & I-NET w/PB & modem only

Just an Addendum to what Nils wrote: We are using SQL-Retriever over dial-up modem lines, it does not require slip or ppp to make this happen, Visionware obviously put a lot of effort into making it this way, presumably to cut out a protocol layer and improve performance.
