My TS-7800 is working pretty well, but I have run into a funny
problem. Two actually!
1) What is the correspondence between the hardware port numbers as
given in the table in the TS-7800 manual, and the device names under
Linux?
I know that the two serial ports implemented in the processor chip are
/dev/ttyS0 and ttyS1
But for the 10 serial ports implement4ed in the FPGA, the port numbers
run 0 through 9. What are their corresponding /dev names?
Do I have to do anything special to activate the ports? I see in the
manual about the various registers, but I was wondering what Linux
does by default.
2) I only need one serial port for the user console, but I need
several to connect to various sensors. I went into /etc/inittab and
disabled the getty on ttysS1. Then I was able to use C-Kermit to talk
to a device wired to COM2. But when I wired a device to COM3 and tried
to open /dev/ttyS2, Kermit refused because the port was not a terminal
device. Specifically, the code calls isatty(), and it returns false.
Thanks!
