"stty crtscts" appears to have turned on handshaking; however when we monitor
the CTS
line with an oscilloscope, the TS7260 still ignores the radio's "not clear"
signal (ie it
continues to transmit data) and we're still dropping bits.
We set both ports ttyAM0 and ttyTS0 - below is a screen capture of our ttyAM0
configuration:
sh-2.05b# stty -a -F ttyAM0
speed 115200 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^X; eof = ^D; eol = <undef>; eol2 =
<undef>;
start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = <undef>;
flush = ^O;
min = 1; time = 0;

Are there any known issues with the ttyAM0 port ignoring CTS/RTS signals?
thanks!
