Sometimes it doesn't pay to get up out of bed. About a month ago I sent out an error fix for conn.c when compiled with FANCYARGS defined. I made a small error. Herein is a rerun of the fixes, correctly this time (I hope). It seems that when you define FANCYARGS so that you can use the neat stuff in getargs.c (well, some of us *have* to) then the "" argument used in L.sys to mean "expect nothing" (or "send nothing") gets broken, because sendthem and expect in conn.c test for "" explicitly, and not for a zero length string. The fix is to simply insert a test for zero length of the input string, and to: expect: just return: if (strcmp(str, "\"\"") == SAME) return(0); ----- if (strlen (str) == 0 || strcmp(str, "\"\"") == SAME) return(0); sendthem: send a newline, then return: /* If "", just send '\r' */ if (strcmp(str, "\"\"") != SAME) ----- /* If "", just send '\r' */ if (strlen (str) != 0 && strcmp(str, "\"\"") != SAME) Formerly, I had checked for a zero length string at the beginning, and then just returned out of sendthem; however, the proper interpretation of "send nothing" should be "send a blank line", ie, a newline character, as I would have known if I had examined the code closer (there's even a comment about it, fer cats sake!) Oh, well, better luck next time. -- Lyle McElhaney (hao,brl-bmd,nbires,csu-cs,scgvaxd)!denelcor!lmc
