How to setup a DigiBoard PC/8

Post by Bruce Guent » Fri, 28 Aug 1998 04:00:00



Greetings.

I am trying to set up a pair of DigiBoard PC/8 (the old ones -- not a
PC/8e, PC/8i or anything like that) in a pair of computers.  I am having
trouble figuring out how to configure Linux to drive these cards.  Do I
need to download a special driver for it (the one in the kernel doesn't
support the plain PC/X series) or what?

Thanks in advance.

Get the driver from  http://www.dgii.com/  
Make sure your digi board(s) is installed in the machine before you
carefully read the install instructions and install the driver and
assorted files it needs.

1. Digiboard PC/8 setup--help!

I'm trying to get a Digiboard PC/8 unintelligent multiport serial board
running as terminal connections.  I've read through the Serial HOWTO and think
I've got every thing set properly, but it's not working.

I created eight cuaX and ttySX devices (starting at X=4) using these commands:

mknod -m 666 /dev/cuaX c 5 <X+64>
mknod -m 666 /dev/ttySX c 4 <X+64>

I then changed the ownership and permissions so these devices are the same as
cua0-3 and ttyS0-3.  The ttySX devices lose read permission for group and
other whenever I shutdown the system.

My getty_ps is compiled as FSSTND compliant.  I have no config files for any
of the devices, depending on defaults for the initial settings.  I'm using
this line in gettydefs for my settings:


These are the lines in rc.serial that I'm using to set up the PC/8 board:

setserial /dev/ttyS4 ^fourport uart 16450 port 0x100 irq 5
setserial /dev/ttyS5 ^fourport uart 16450 port 0x108 irq 5
setserial /dev/ttyS6 ^fourport uart 16450 port 0x110 irq 5
setserial /dev/ttyS7 ^fourport uart 16450 port 0x118 irq 5
setserial /dev/ttyS8 ^fourport uart 16450 port 0x120 irq 5
setserial /dev/ttyS9 ^fourport uart 16450 port 0x128 irq 5
setserial /dev/ttyS10 ^fourport uart 16450 port 0x130 irq 5
setserial /dev/ttyS11 ^fourport uart 16450 port 0x138 irq 5

These are the lines in inittab that I thought would set the lines up for
login:

# Run gettys in standard runlevels
1:12345:respawn:/sbin/mingetty tty1
2:2345:respawn:/sbin/mingetty tty2
3:2345:respawn:/sbin/mingetty tty3
4:2345:respawn:/sbin/mingetty tty4
5:2345:respawn:/sbin/mingetty tty5
6:2345:respawn:/sbin/mingetty tty6
S4:2345:respawn:/sbin/getty ttyS4 DT9600 vt100
S5:2345:respawn:/sbin/getty ttyS5 DT9600 vt100
S6:2345:respawn:/sbin/getty ttyS6 DT9600 vt100
S7:2345:respawn:/sbin/getty ttyS7 DT9600 vt100
S8:2345:respawn:/sbin/getty ttyS8 DT9600 vt100
S9:2345:respawn:/sbin/getty ttyS9 DT9600 vt100
S10:2345:respawn:/sbin/getty ttyS10 DT9600 vt100
S11:2345:respawn:/sbin/getty ttyS11 DT9600 vt100

When I look at the process table, the TTY entry for these lines all are ?.
When I connect a terminal to any of the lines, all I get (regardless of
whether I have a straight-through or a null-modem cable) is a degree symbol
for the lowercase letters e,r, and t and a capital C cedilla (that's the
little curl under the letter) for a lowercase s.

I'm sure I'm overlooking something obvious; it's been quite a while since I
configured serial ports on Unix-like systems (not since Xenix, actually).  I'd
appreciate any help I could get.
