Kabel Dudul,
keinget, waktu lab kemaren. udah jelas pake kabel v35 male, tapi kok pas di show controller nongolnya begini:
SLM-DC-LAR1#sh controllers s0/1
Interface Serial0/1
Hardware is GT96K
DTE V.24 (RS-232) clocks stopped.idb at 0x633CEED8, driver data structure at 0x633D6C74
wic_info 0x633D71D0
Physical Port 0, SCC Num 0
ini tanda-tanda kabelnya rusak, alias dudul. setelah diganti, langsung tokcer :)
