Public bug reported: Binary package hint: minicom
[EMAIL PROTECTED]:~$ lsb_release -rd Description: Ubuntu 8.04.1 Release: 8.04 [EMAIL PROTECTED]:~$ apt-cache policy minicom minicom: Installed: 2.3~rc1-2 Candidate: 2.3~rc1-2 Version table: *** 2.3~rc1-2 0 500 http://us.archive.ubuntu.com hardy/main Packages 100 /var/lib/dpkg/status The reason I included this next package is the cypress files are part of it. [EMAIL PROTECTED]:/home/lbergman# apt-cache policy linux-headers-2.6.24-19-generic linux-headers-2.6.24-19-generic: Installed: 2.6.24-19.34 Candidate: 2.6.24-19.34 Version table: *** 2.6.24-19.34 0 500 http://us.archive.ubuntu.com hardy-updates/main Packages 100 /var/lib/dpkg/status Ubuntu 8.04 updated today. I expected to get a blinking cursor and then to hit enter a couple of times to start the connection. Instead, what I got follows. The USB to Serial device appears to be recognized and configured normally. a device is created at /dev/ttyUSB0. Upon starting minicom with a config to use the ttyUSB0 port minicom freezes with the standard "initializing modem" box on the screen and remains until the usb device is unplugged. Immediately after unplugging the device the terminal reports "Minicom: Device disappeared, aborting!" and returns control to the terminal. I have not tried to use pyserial or any other serial control program to check if it is a minicom or hardware issue. I could find no markings to positively identify the hardware as being what is reported via dmesg and messages. I looked through dozens of bugs and found references to brltty and removed this package which had no impact on the results. Here is some output to shed some light. minirc: [EMAIL PROTECTED]:~$ cat /etc/minicom/minirc.dfl # Machine-generated file - use "minicom -s" to change parameters. pu port /dev/ttyUSB0 pu baudrate 9600 /etc/minicom/minicom.users: The only uncommented entry is the following: # Everyone has access to all configurations.
