19 Options:-
20 -a, --all Write all current settings to stdout in human-readable form.-
21 -g, --save Write all current settings to stdout in stty-readable form.-
22 -F, --file Open and use the specified device instead of stdin-
23-
24 If no args are given, write to stdout the baud rate and settings that-
25 have been changed from their defaults. Mode reading and changes-
26 are done on the specified device, or stdin if none was specified.-

1738 The following code deals with a bug in the SunOS 4.x (and 3.x?) kernel.-
1739 This comment from sys/ttold.h describes Sun's twisted logic - a better-
1740 test would have been (ts_lines > 64k || ts_cols > 64k || ts_cols == 0).-
1741 At any rate, the problem is gone in Solaris 2.x.-
1742-
1743 Unfortunately, the old TIOCSSIZE code does collide with TIOCSWINSZ,-
1744 but they can be disambiguated by checking whether a "struct ttysize"-
1745 structure's "ts_lines" field is greater than 64K or not. If so,-
1746 it's almost certainly a "struct winsize" instead.-
1747-
1748 At any rate, the bug manifests itself when ws_row == 0; the symptom is-
1749 that ws_row is set to ws_col, and ws_col is set to (ws_xpixel<<16)-
1750 + ws_ypixel. Since GNU stty sets rows and columns separately, this bug-
1751 caused "stty rows 0 cols 0" to set rows to cols and cols to 0, while-
1752 "stty cols 0 rows 0" would do the right thing. On a little-endian-
1753 machine like the sun386i, the problem is the same, but for ws_col == 0.-
1754-
1755 The workaround is to do the ioctl once with row and col = 1 to set the-
1756 pixel info, and then do it again using a TIOCSSIZE to set rows/cols. */-
