Hi,
I've written a short script in pexpect to open the serial port and get 100 bytes. The script does receive a string of garbage, but not the good text seen when I open a minicom terminal and look at ttyS0.
I know that the baud rate is wrong, and the other settings (such as 8N1) are unknown to me and may also be wrong.
Question: In Linux, how do I set the baud rate = 19200, 8N1 in pexpect scenario? (this example is close to the pexpect documentation, but I used the fdpexpect.fdspawn extension because pexpect.spawn didn't work.
#!/bin/python
import pexpect
import os
import fdpexpect
fd = os.open("/dev/ttyS0", os.O_RDWR|os.O_NONBLOCK|os.O_NOCTTY )
m = fdpexpect.fdspawn(fd) # Note integer fd is used instead of usual string.
m.send("+++") # Escape sequence
m.send("ATZ0\r") # Reset modem to profile 0
string1 = m.read(100)
print "%s" % string1
Would the baudrate setup be similiar under windows? Any examples out there?
In short, setting of critical parameters is unclear under pexpect's documentation, but may be obvious to those more familiar with os.open or other filesystem internals.
Thanks,
Bryce
