How to work "ct" on IRIS

[Yasuhiko Watanabe]

I tried to connect modem to SGI serial port, and fix hayes modem setting by
fix-hayes, edit inittab, and tried telinit q.
After these work, I edited the Devices. But ct prints out "no modem."(I do
not remember the exact message) Why? I am using IRIX3.3.2.
Does ct really look Devices file? Or are there any files to be modified?
