Occasionally my Unix PC's internal modem locks and will not dial out or
answer the phone while it's in data mode. Sometimes this can be fixed
by toggling the line to voice and then back to data, but uucp (I have
the store's HDB uucp installed) doesn't recognize this. The only
solution I've found is to shut the system down and restart it. Are
there any control codes I can send the modem to get it to reset itself
without a shutdown? I want to run the system as a BBS again, and would
like to periodically reset the modem to be sure that outside callers can
dial in.

/etc/rc runs a 68K executable file named /etc/.modeminit. .modeminit seems to do some magic to initialize the OBM. It doesn't seem to do any harm to run .modeminit as long as there isn't any ongoing phone activity. I just tried running it, and it clicked some realy, but not the line relay as the click was softer than the clanking sound the line realy makes on my machine. The ultimate test was that the OBM still worked afterword. As usual, .modeminit doesn't seem to be documented; at least if it is lurking in the manuals, it has eluded my search thus far. Here is a strings of .modeminit: --------------------------------- .data PN^Nup XON^Nu /etc/.lineone /etc/.linetwo /dev/ph1 /dev/ph0 Failed to open modem port.
