serial port rate - Hardware
This is a discussion on serial port rate - Hardware ; Hi, I wrote a script wherein part of its thing is to disconnect a call.
Every time I try I get
kernel: pl2303 ttyUSB0: pl2303 driver does not support the baudrate requested (fix it)

serial port rate
Hi, I wrote a script wherein part of its thing is to disconnect a call.
Every time I try I get
kernel: pl2303 ttyUSB0: pl2303 driver does not support the baudrate requested (fix it)
I've tried different methods:
1:
{
echo at h1
sleep 1
echo at h
} > /dev/ttyUSB0
2:
echo at h1 > /dev/ttyUSB0
sleep 1
echo at h > /dev/ttyUSB0
3:
chat '' 'at h1' 'OK' '' < /dev/ttyUSB0 > /dev/ttyUSB0
sleep 1
chat '' 'at h' 'OK' '' < /dev/ttyUSB0 > /dev/ttyUSB0
and all produce the error. (The last one also worked the last time it
ran; I don't know if that was a fluke or not.)
So how can I make this not happen? I looked for setserial, but it's not
on my system. Would it do what I want?

AFAIK a
kill -1 (Process-id of corresponding process, eg.
mgetty, pppd etc. figure it out with "fuser /dev/ttyUSB0" )
would be apropriate.

No. setserial is for changing parameters (eg. flow-control, baud rate
etc.) of the serial port.
Hanging up a connection is a different thing. However, if you want to
play with it just g**gle for it, download, chmod +x and have fun.
