  91. D. Installation
  92.  
  93. D.1 Driver install
  94. Please create a directory under root directory, e.g /temp, do commands:
  95.  
  96. # cd /
  97. # mkdir temp
  98.  
  99. After get driver file "wch_vx.x.x.x.tar.gz". Copy file to /temp
  100. directory, then extract and install, do commands:
  101.  
  102. # cp wch_vx.x.x.x.tar.gz /temp
  103. # cd /temp
  104. # tar xvfz wch_vx.x.x.x.tar.gz
  105. # cd /temp/wch
  106. # make clean ; make install
  107.  
  108. *************************************************************
  109. * If system is Suse 9.0 and errors occur when *
  110. * "make clean ; make install", do commands: *
  111. * *
  112. * # cd /usr/src/linux/ *
  113. * # make cloneconfig *
  114. * # make dep *
  115. * *
  116. * then do "make clean ; make install" again in /temp/wch *
  117. *************************************************************
  118.  
  119. Load driver module, do command:
  120.  
  121. # modprobe wch
  122. or
  123. # insmod /temp/wch/driver/wch.ko (wch.o for kernel 2.4)
  124.  
  125.  
  126. Check driver module, do command:
  127. # lsmod | grep wch
  128.  
  129.  
  130. Unload driver, do command:
  131. # rmmod wch
  132.  
  133.  
  134. D.2 Device node creation
  135. Each serial port has one device node which is named "ttyWCH?",
  136. maximum up to 256 serial ports.
  137.  
  138. This setp will be done when do "make clean ; make install", if
  139. device nodes aren't in /dev, do commands:
  140.  
  141. # cd /temp/wch/wchmknod
  142. # ./wchmknod
  143.  
  144. This will create device nodes in /dev.
