Programming Forum and web based access to our favorite programming groups.i got a multi-port serial card (MSC) connected to a mother board via PC/104 ISA bus. there are eight serial ports on the MSC, but any of them can only be associated with ttyS2 or ttyS3 (i did not tried ttyS0,1 for they are already used by the mother board itself). if i associated (via setserial command) an y of them to ttyS4+, a very _long delay_ will be detected on both direction of RX and TX. those ports all shared a common irq (not occupied by other devices) but with different io base address. i doubt there is a kernel configuration problem, but i just have no a clue. the version of linux kernel is 2.2.x (yes, it too old, but we used it with some other brand of multi-port serial boards w/o problem). any clue? thanks in advance. -- steven woody (id: narke) Angelica Bell: What happens to us when we die?

Some multi-port cards use their own device names rather than ttyS*. See devices.txt.gz in your kernel documentation. I don't know about Slackware, but in Debian-based systems, when you install the kernel-doc package, the docs are in /usr/share/doc/kernel-doc-(version)/Documentation, or linux-doc-(version) for newer kernels. -- Men of quality are not afraid of women for equality.
