I'm using a Smart One 2400 hayes compatable modem. I have it setup so that the modem answers properly, but as soon as the modem answers, I get a console message: serial: ERROR: Garbage or loose cable on dev 0, port shut down getty doesn't seem to function if I do: stty </dev/tty1A after this message then getty will function and the user can login. Any ideas? J -- ============================================================================== Jay A. Snyder "Let Me Up! I've had enough" wa3wbu!gdx!jay@uunet.uu.net uunet!wa3wbu!gdx!jay

If you are using an internal modem, this is quite difficult :-) Install xnx155b (available FREE from SCO or your local distributor). Among other things, it will fix the "serial: ERROR: Garbage or loose cable on dev 0, port shut down" error.

If not, your modem would, prior to rising the DTR line, send character replies to getty, which does not expect to receive data (no DTR!). So getty treats this data as garbage from the line and therefore closed down the line. rgds Ralf Holighaus -- Programmentwicklung fuer Microcomputer | Ralf U.

The problem with with the ring detect line. Apparently, the SCO tty drivers don't know how to handle the ring detect interrupts, and barf when they get them. I have been informed that there is a fix (xnx128) for this from SCO: Dear SCO Customer, Enclosed is Support Level Supplement (SLS) xnx128. This floppy contains a set of modified SCO XENIX files which will allow an internal modem to answer incoming calls. Previously the error message "Garbage or loose cable on serial dev <x>, port shut down" was displayed on the console when ever the modem attempted to answer a call. Serial dev <x> is either a zero or eight. Zero for /dev/tty1a (COM1), or eight for /dev/tty2a (COM2). This supplement is for SCO XENIX 286 Operating System Release 2.2.3 and SCO XENIX 386 Operating System Release 2.3.0, 2.3.1, 2.3.1 only. In order to install this supplement, the Link Kit must be installed. If the Link Kit is not installed on your system, or if you are not sure, refer to custom(C) in your SCO XENIX System V Operating System User's Reference manual. To install this supplement, please follow the steps outlined below: 1. Login as root. 2. Make sure that you are in the root directory. cd / <RETURN> 3. Type the command: /etc/install <RETURN> 4. Type "y" at the prompt for the first floppy. 5. Follow the instructions on the console. 6. Reboot the machine using the reboot(C) command: /etc/reboot <RETURN> If you have any questions, please call our Customer Services Department at (800) 626 - 4381. SCO Customer Service is available Monday through Friday, 6:00 A.M. to 5:00 P.M., Pacific Time. We appreciate your business. SCO Support Services JG:akb/4-89 xnx.128:rev.a
