I change ser_fet_buf function with ser_get_buf_len

And this is the debug output:

Network UPS Tools - Liebert GXT2 serial UPS driver 0.02 (2.4.3)
Warning: This is an experimental driver.
Some features may not function correctly.

   0.000000    debug level is '2'
   0.020847    send: (6 bytes) => 01 88 02 01 04 90
   1.020588    read: truncated: (0 bytes) =>
   1.020604    GTX2 capable UPS not detected
