What does the serial driver report when Linux boots? It should report
ttyS0 and ttyS1, their I/O base, their IRQ, and the UART type. If you
don't see such messages as you boot, either the serial ports are broken
or disabled, or you recompiled the kernel forgetting the serial driver.

It may be that you simply have to play with setserial. Sometimes a
16550A UART will cause mouse problems. Using setserial to tell Linux
that the UART is an 8250 or 16450 usually cures the problem.

 
 
 

1. HELP : Cyrix + ASUS HX + serial

I have trouble with a new motherboard (ASUS with chipset 430HX).
the system came with a 8x86 200+ (75/150 Mhz).

It seems like ttyS0 (and probably ttyS1, but I have not tested)
doesn't work : no mouse in X, nothing with od /dev/mouse...
I tested a Microsoft compatible mouse and a Logitech Mouseman.

On the other hand, Windows NT works well... And Linux itself is
OK.  X functions with the old Pentium 100 motherboard. Is there some
incompatibilities between Linux serial drivers and the hardware ?
Or has anybody found the same problem ?
