TTYTERM : additional info Updates ======= Between each offical release, the latest sources are available from CVS. Click on "Code / web-based CVS repository viewer" to view the history for each file. Click on "Download GNU tarball" to download all the files at their latest revision. Troubleshooting =============== --- Non functional local serial port --- When using a local serial port (onboard or USB adapter), the current stty settings for this port may prevent the port from working properly. For example the port may be configured to wait for DCD to become active but unfortunately your cable wiring does not manage this signal. An easy way to recover is to use the following stty command before opening ttyterm on it (example for ttyUSB0 device) : $ stty -F /dev/ttyUSB0 0:4:1cb2:8a30:3:1c:7f:15:4:0:1:0:11:13:1a:0:12:f:17:16:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0:0 This will set the port to 115200 bauds, 8 bit, 1 stop bit, no parity, no hardware flow control, ..., and some other sane settings. If an error occurs when running this command, try tu run it once again. Then, if needed, set the baudrate to the required value, for example 9600 : $ stty -F /dev/ttyUSB0 9600 --- Strange behaviour when using telnet to connect to a serial port --- Depending on the telnet server of the serial port, it may be needed to force the following modes on the client side (on the machine running ttyterm) : mode char : Disable the TELNET LINEMODE option, or, if the remote side does not understand the LINEMODE option, then enter ‘‘character at a time’’ mode. set binary : Enable the TELNET BINARY option on both input and output. This can be specified in a ~/.telnetrc file as follows : # cat ~/.telnetrc serialservername mode char set binary
