I have an old 300/1200/4800/9600 modem sitting around the house. It occurs to me that a modem and a TNC perform the same basic type of operations. Are these two units similar enough that I could convert an old modem to be a dumb TNC? -- William McKeehan KI4HDU Internet: mckeehan at mckeehan.homeip.net http://mckeehan.homeip.net
