Serial Configuration

[Jake Griesbach <griesbac@gamera.colorado.edu>]

Hi,

I eventually want to connect a 14400 modem to my SparcStation 1+ running
SparcLinux.  I'm having trouble configuring the serial ports.  First of
all, does this have to be done?  I have noticed that I can do some
configuration from the prom.

During boot, setserial runs and gives an error.

I have tried the following command, but to no avail:

setserial -b /dev/ttyS0 irq 12 port 0xffd02004 skip_test autoconfig \
session_lockout spd_normal

which returns:  Cannot set serial info:  Invalid argmuent

the kernel reports on bootup:

Sparc Zilog8530 serial driver version 1.38
tty00 at 0xffd02004 (irq = 12) is a Zilog8530
tty01 at 0xffd02000 (irq = 12) is a Zilog8530
tty02 at 0xffd00004 (irq = 12) is a Zilog8530
tty03 at 0xffd00000 (irq = 12) is a Zilog8530

Does the kernel perform the necessary configuration for Sparcs?

Thanks,
