There's an USB/Serial converter connecting two boxes.
Box A has USB end, box B has serial port end.
On box A:
screen /dev/ttyUSB0 9600
On box B (the one I'm trying to connect to from box A):
/etc/inittab: ... T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100 ...
What I write to /dev/ttyS0 on box B is seen in the terminal on box A (via screen),
but data written to dev/ttyUSB0 on box A is not received on box B, for example, I can't type anything, though I see the login promt.
Any ideas? Thanks
EDIT1:
I've tried minicom and picocom with same results as above.
Here's the output of lsusb on box A:
Bus 005 Device 002: ID 14dd:0002 Bus 005 Device 001: ID 0000:0000 Bus 004 Device 001: ID 0000:0000 Bus 002 Device 001: ID 0000:0000 Bus 003 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port Bus 003 Device 001: ID 0000:0000 Bus 001 Device 001: ID 0000:0000
EDIT2:
Output of DMESG on box A:

EDIT3:
box B (I've increased baud rate since):
stty -a -F /dev/ttyS0 speed 115200 baud; rows 0; columns 0; line = 0; intr = ^C; quit = ^\; erase = ^?; kill = ^H; eof = ^D; eol = ; eol2 = ; swtch = ; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0; -parenb -parodd cs8 hupcl -cstopb cread clocal -crtscts -ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr -icrnl -ixon -ixoff -iuclc -ixany -imaxbel -iutf8 -opost -olcuc -ocrnl -onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 -isig -icanon -iexten -echo -echoe -echok -echonl -noflsh -xcase -tostop -echoprt -echoctl -echoke
Running screen with such params on box A ends the same way:
