I would like to configure the ports on our Develcon dataswitch to allow outgoing calls. If I do not make the ports answer only, the when getty raises carrier by opening the tty line, the switch sees this and connects the line to an SPS. After 15 seconds, the dataswitch will drop carrier. Getty takes this as a terminal being turned off. Getty will then open the tty line again and the cycle is repeated. Has anyone out there gotten aroung this problem? Derek Andrew Univ of Saskatchewan

We eliminated the signal cycle problem at our site by changing the init entry in /etc/inittab from 2 to 9. This has the effect of ignoring the signals generated by Develcon at the UNIX end. Our only problem now is having UUCP say the correct things to Develcon to establish a path through the Dataswitch. Bill Beblo Bell Labs - Murray Hill (201)-582-7365

We have a version of uucp that knows its way through the dataswitch. The problem is not too difficult. One must be able to specify delay, and the transmission of arbitrary sequences which my not end with a carriage return/newline in L.sys

What dale said in Article 40 is correct. However, I think what you are looking for is a general approach. The approach you should take is that you have to permanently assign lines from the com- puter to the dataswitch as outgoing only. This means that the "getty"s must be turned off. Then when you "open" the line, DTR goes up and the switch responds(hopefully) with CD. This completes the open and then you either do uucp/cu stuff or your own. Hope this helps. cbosg!sparky alias Norm Thompson
