I try to get serial communication with a broadbandrouter When i use PCPLUS with DOS 5.0 i can get communication with the router (115200 N81 No Software Control / No hardware Control) It works both on comm1 and comm2 If i try to communicated from Fedora 6 with minicom I get for ttyS1 --> device does not exist for ttyS0 --> i get nothing If i look at the /dev directory i see the devices ttyS0 to ttyS3 (with dev ttyS0 connected) crw-rw---- 1 root uucp 4, 64 mrt 28 15:24 ttyS0 crw-rw---- 1 root root 4, 65 mrt 28 2007 ttyS1 crw-rw---- 1 root root 4, 66 mrt 28 2007 ttyS2 crw-rw---- 1 root root 4, 67 mrt 28 2007 ttyS3 Where do i have to look, to make the serial connection work on comm1 (ttyS0). Thanks Erik
