sbserial

sbserial starts the serial terminal program seyon with a preset baud rate on a preset serial port.

The baud rate and port are read from config files located in $HOME/.config/sbserial/<name>. Start the script with the name of the config file as the only parameter eg.:

sbserial usb

If no config file is specified or it cannot be found, sberial expects the baudrate in arg 1 and devicefile in arg 2, eg.:

sbserial 115200 ttyS0

Notes:

• Do not forget to add yourself to the group which has permission to use the serial device files ttyS0, ttyUSB0 etc. On Slackware this is the group dialout
• If you do not have a real RS232 interface anymore, you can use an USB-to-serial adapter. After pluggin into the USB port, usually the file /dev/ttyUSB0 is created by the kernel. This can be used just the same way as the „real“ ttyS0.

#!/bin/bash
# file: $HOME/.config/sbserial/usb
baud='19200'
device='ttyUSB0'

#!/bin/bash
# file: $HOME/.config/sbserial/38400
baud='38400'
device='ttyS0'
