I'm running some CableEye software and connected to a cable tester via ttyS0. I've migrated an old p3 box to a newer (still old but) Dual P4 2.2GZ processor. Everything works but the serial port is too slow. The old p3 would test a cable in a second. Now in the emulator it takes 8 seconds to test the same cable. I have tried these 2 combos with no luck $_ports = " device /dev/null range 0x3f8 0x3ff fast" # $_com1 = "/dev/ttyS0" and #$_ports = " device /dev/null range 0x3f8 0x3ff fast" $_com1 = "/dev/ttyS0" They act the same. How can I get this thing to sing? Thanks in advance Mark
