hello, I am having some problems with my serial ports...
>From ls -l /dev/ttyS* shows.. crw-rw---- 1 root dialout 4, 64 Jul 5 23:14 /dev/ttyS0 crw-rw---- 1 root dialout 4, 65 Jul 5 23:14 /dev/ttyS1 crw-rw---- 1 root dialout 4, 66 Jul 5 23:14 /dev/ttyS2 crw-rw---- 1 root dialout 4, 67 Jul 5 23:14 /dev/ttyS3 but setserial -agv /dev/ttyS* shows... /dev/tty0: No such device /dev/tty1: No such device /dev/tty2: No such device /dev/tty3: No such device Also, during boot-up I get: modprobe: can't locate module char-major-4... Question: why doesn't my serial ports get recognized? I tried upgrading to a newer setserial then setting it via #setserial /dev/ttyS0 or setserial /dev/ttyS1, etc... but I still get no such device perhaps I am passing setserial command with wrong parameters/arguments? if so, how should I use setserial to fix this problem or should I use a different approach? Hoping for some advice Thank you.
