Re: [Linux-gpib-general] Installing DKMS driver on Ubuntu 26.04

[David G. <dav...@po...>]

Thanks Dave,

Getting closer, but still not loading as CIC not set on the board and 
timeout isn't 3 seconds as configured.

$ ibterm -m 0 -d 25
Attempting to open /dev/gpib0
pad = 25, sad = 0, timeout = 10, send_eoi = 1, eos_mode = 0x0000

ibterm error: Unable to write to device at pad 25

Should I set that for earlier in the boot process?
