We're getting repeated serial faults when attaching a printronix to a SUN 3. The printronix will occasionally be able to print small files such as 1K or 2K of ascii, but when we go up to 10K, we get the serial fault error on the printronix error display. The line between the sun 3 and printronix is a fresh null-modem line with pins 2 and 3 swapped. Serial port b (/dev/ttyb) has been designated as the printer port and shares the same major and minor device numbers as /dev/lp0. Files get correctly queued in /usr/spool/lp0, a lock file gets created, but it just won't go beyond the 1K or 2K file-length before getting the serial fault. Any suggestions? Stuart P.S. Oh, by the way, the same printronix works perfectly on another identically configured SUN 3.
