- Did an answer to this earlier article get posted? I could also use
- similar information. My uucico and getty sessions aren't hung up properly;
- I notice this because I have a similarly-misconfigured modem on the other
- side (a 3.2 UNIX whose serial cable I still need to tinker with).
-
- If I run 'kermit' on the Linux system, I note that DTR is dropped for about
- 500ms if I type the hangup command to it. But if I remote login to the
- modem, DTR remains high when I log out. I'm running with the H.Lu release
- 0.98pl5 dating back a few weeks.
-
- In answer to Gary's question above, a lot of modems come factory-
- configured to ignore the state of DTR. Look for the "&D" setting in
- your modem; mine was indeed &D0 before I changed it. Some modems show
- the state of DTR in a front-panel LED; try running the same test I did
- with Kermit to see if the signal is dropped. (I won't buy internal
- modems 'cause it's hard to diagnose problems and 'cause you can't reset
- them without rebooting the computer. With a little shopping, I found
- an external 14.4K modem for less than most internals.) For about US$10
- you can get an RS-232 signal indicator from places like Radio Shack; it's
- an invaluable tool.
-
- I also note that the standard getty configuration seems not to work with
- a hardwired local terminal because getty changes the clocal stty setting.
- When I get some time I'll download the source to getty and alter this
- logic.
