- Frequently Asked Questions about Minicom:
- Q1: Why does my modem respond so SLOWLY to everything I type? Even the init
- string seems to pause for seconds between each character.
- A1: This is not actually a Minicom problem, but a hardware problem. You
- have an interrupt conflict in your computer. That means, some other device
- is using the same IRQ as your modem. This happens quite often if you have
- an internal modem set up as /dev/ttyS2 or /dev/ttyS3 (also known as com3 or
- com4 on some other operating systems). By default, /dev/ttyS0 and
- /dev/ttyS2 (or com1 and com3) use IRQ 4 and /dev/ttyS1 and /dev/ttyS3 (or
- com2 and com4) use IRQ 3. So, if you have an internal modem, disable the
- serial port using the same irq on your motherboard or i/o card (check the
- motherboard manual), or change one of the ports to use some other irq
- (probably with the setserial command in /etc/rc.d/rc.local or some other
- bootup script).
- Q2: When I try dialing out, minicom just says "you are already online" and
- refuses to dial. Why does it do that and what should I do?
- A2: Since version 1.82, Minicom doesn't begin dialing if the modem says that
- you are online by keeping the carrier signal on.
- Maybe your modem always keeps the carrier signal on. Consult the manual of
- your modem for the right command to use the carrier signal properly.
- On my modem, the command would be at&c1 but it may be different in your
- modem. Save the changed modem settings or add &c1 (or whatever it is) to
- your init string.
- If your modem is broken and can't handle the carrier signal, you may set
- minicom to ignore DCD by going to the "modem and dialing" settings and
- turning off the "Modem has DCD line" setting.
