I am interested in knowing if anyone has added a modem to a VAX running 4.3 BSD that functions as a dialup and dialout. I have added a modem to a Sun system that allows the one modem to work as a dialup and a dialout by setting the major number and minor number to a particular value that will allow the same particular port to function as a dialup and dialout. For instance, in my case I made a new device file for the same port. /dev/ttya was major number 12, minor number 0; I made device /dev/cua0 with major number 12, minor number 128. I changed ownership to the right owner, added a getty to the appropriate device and ... it worked. Of course I did have to enable hardware flow control for the port. I have spent some time digging in the source of conf.c to determine the correct value for the minor number of this additional device for a BSD system on the VAX, but cannot distinguish it. If anyone has done this or knows the correct minor number to do this (assuming it is possible at all), or just has some insight as to how I might determine this number, any assistance would be greatly appreciated?
