Subject: [PATCH] Output newline on stdout with hex print mode

This is to fix the issue #104. The timestamp will always be
printed at the beginning of line:

[10:25:56] Switched to hexadecimal mode
0d 0a 0d [10:25:57] 41 43 52 4e 3a 5c 3e 0d 0a 0d [10:25:58] 41

is changed to:

[12:34:56] 45 72 72 6f 72 3a 20 49 6e 76 61 6c 69 64 20
[12:34:56] 41 43 52 4e 3a 5c 3e
[12:34:56] 41 43 52 4e 3a 5c 3e
[12:34:57] 41 43 52 4e 3a 5c 3e 6c 73
