I have a 6 port boca IOAT66 serial port card. The linux hardware howto
says that this card can be used with linux, but I am having trouble configuring
it.
The description in the manual says that it uses port 0x208
as a shared port. Each bit in the port corresponds to an interupt
on a port:
Bit 76543210
Port **FEDCBA
* unused and always one
[A-F] identify a given port
When the interrupt is active, the bit which identifies the port is set to 0.
When I boot the system, the ports are noticed, but are given incorrect
settings. If I issue the command
setserial -v /dev/cua32 irq5 port 0x220 set_multiport \
port1 0x208 mask1 0x3f match1 0x3f
I can connect to the serial device on port A with minicom.
There is another computer at the other end of the link, and when
I send something from this other computer, the entire message is
received by the linux box, but as soon as it stops transmitting,
I get beeps and garbage on the linux machine. I don't seem to be
able to receive anything from the linux box on the other machine.
What am I doing wrong?
Here are the settings for the card:
Port ADDR
A 220
B 228
C 240
D 248
E 260
F 268
Shared IRQ 5
Int. Stat. ADDR 208
This is the message that is given at boot
Serial driver version 4.13 with no serial options enabled

tty01 at 0x02f8 (irq = 3) is a 16550A

tty36 at 0x5220 (irq = 3) is a 16550A
