I tested it (in 1887) without the cr/lf and in 1888 with cr/lf, but I
always get the following:

[rfu at helios drivers]$ ./ivtscd -DDD -a ivtscd
Network UPS Tools - IVT Solar Controller driver 0.01 (2.4.1-1888)
Warning: This is an experimental driver.
Some features may not function correctly.

   0.000000     debug level is '3'
   0.001845     send: F
   0.364839     read:
   0.364937     IVT Solar Controller not detected

I checked the baud rate with stty and it is set to 1200, so this shouldn't
be the problem.

enjoy your vacation ! I'll dig into the source code tomorrow and see where
the response gets lost.
