====== sbserial ==
===== Description ==

''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''.

===== Conifg File Examples ==

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

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