Replace line 18 with #define tperr stderr and it'll build. It looks like you may also want to edit tploc.h, line 49, and replace those two "8"'s with "%d"'s. Then something like "cptp -m 0 of=- | cptp -m 1 if=-" should copy from rmt0 to rmt1 with a little bit of pipe buffering inbetween. Adding "team" or "buffer" (both in ports/misc) inbetween will add even more buffering. -- Dan Nelson dnelson@allantgroup.com
