yes: keep exactly this sequence:
1st: unload serial driver and any software which might use it .
2nd: enable/disable or reconfigure the seriral ports as desired.
3rd: reload the serial driver.
if there is still no serial port, please check your PCMCIA stuff. if you also
have installed an ethernet card, this card eventually did grab your IRQ3.
Than you also have to disable this IRQ (and perhaps the IO port range) for the
PCMCIA stuff (/etc/pcmcia/config.opts). Don't forget to issue /etc/rc.d/pcmcia
