Re: cannot talk with AT modem

[Tomasz Barszczak]

Well, too soon to be happy.
cron runs periodically rmmod -a .
Then when I want to use the modem again serial driver is re-loaded:
  Serial driver version 4.13 with no serial options enabled
  tty00 at 0x03f8 (irq = 4) is a 16550A
  tty01 at 0x02f8 (irq = 3) is a 16550A
And the modem is inaccessible again.
setserial shows that /dev/ttyS4 reverted to original parameters.
I have to run the setserial command manually again.
How can I fix this?
BTW I have added proper setserial command to /etc/rc.boot/0setserial
as mentioned in the manpage.
Tomasz.
