[Dxspider-support] Com Port Setup

You need the 'setserial' command to place non-standard COM-ports
and IRQ settings...

I use the following to bring up my 4-port serial card in /etc/rc.d/rc.local :

#
# bring up the additional serial ports
#
SETSERIAL="/bin/setserial -abv"
${SETSERIAL} /dev/ttyS4 uart 16550A port 0x1A0 irq 5 fourport
${SETSERIAL} /dev/ttyS5 uart 16550A port 0x1A8 irq 5 fourport
${SETSERIAL} /dev/ttyS6 uart 16550A port 0x1B0 irq 5 fourport
${SETSERIAL} /dev/ttyS7 uart 16550A port 0x1B8 irq 5 fourport


You would want something like:


SETSERIAL="/bin/setserial -abv"
${SETSERIAL} /dev/ttyS2 uart 16550A port 0x3e8 irq 5
${SETSERIAL} /dev/ttyS3 uart 16550A port 0x2e8 irq 7

Check the addresses in the above (I may have them wrong :-)

You may also need to have the kernel compiled to support
more than two comports - depends how mandrake built it.

  Hi All,
           Im running the linux version of dx-spider under Mandrake 8.2.

  I have 4 com ports fitted, two on the motherboard and two on an extra card. I can only get COM1 IRQ4 and COM2 IRQ3 working. I have set COM3 as IRQ5 and COM4 as IRQ7 on the plugin board. Both of these IRQ's are available, but linux is trying to use COM3 IRQ 4 and COM4 IRQ. Does any know how to change the com port irq's within mandrake linux.

  Please note im new to linux, so please try to give full details
