Two modems under diald

I have diald up and running. It works almost out of the box with 1 interface to
bring ppp up. Now I have two modems to dialup (among other things) and I
want diald to use any of them, whichever be free. I succesfully configured pppd
and chat to use any of two interfaces, but when I use diald, it wants the device
locked before calling chat or pppd.

I remember I saw somewhere I have to hack some diald script, but I don't
remember which and how... I'm using diald 0.16.5-5 under RedHat 5.1.

In your diald configuration file, you should specify a line for each modem you want diald to use. So for a system with two modems on com1 and com2 you might have:-

device /dev/cua0
device /dev/cua1

in the configuration file. Diald will sequence through all the specified devices when a link-up request is received, until it finds one that is not locked. When it finds one of these, it will lock the device, and then dial out. The 'lock' keyword in the conf file instructs diald to perform UUCP stlye locking of the serial line. It sounds as though you may wish to turn this off,  though I'm not convinced it's a good idea to do so.

With multiple dial-out device, you probably also want to use the rotate-devices command.

One potential problem - if you have another process listening on the modem, but you want diald to use this modem anyway if a call is not in progress, you might have trouble. If diald can't find a non-locked device in the list, it won't dial out. Getting round this is not a diald configuration issue - you need to tell the listening process to not lock the device until a connection is made. Doing this will be dependant on what software you are using to listen on the modem...
