<p><b>New page</b></p><div>'''Sun Workstations'''<br />
<br />
Use command<br />
<br />
cu -l /dev/cua/a<br />
<br />
where 'a' is port name, can be 'b' etc.<br />
<br />
If does not work, run in debug mode:<br />
<br />
cu -d -l /dev/cua/a<br />
<br />
Observed problems:<br />
<br />
* on ''wolfram'' after Solaris 10 Update 3 installation port 'a' returned following:<br />
<br />
wolfram:/root> cu -l /dev/cua/a<br />
Connect failed: NO DEVICES AVAILABLE<br />
<br />
In debug mode:<br />
<br />

call cleanup(1)<br />
call _mode(0)<br />
<br />
Found on web:<br />
<br />
The standard uucp configuration files do not have entries for port ttya.<br />
This will cause cu to fail:<br />
# /usr/bin/cu -l /dev/cua/a<br />
Connect failed: NO DEVICES AVAILABLE<br />
The debug mode of cu shows the problem:<br />
# cu -d -l /dev/cua/a<br />
altconn called<br />
Device Type Direct wanted <== no "Direct" in /etc/uucp/Devices<br />
Requested Device Type Not Found<br />
getto ret -1<br />
Connect failed: NO DEVICES AVAILABLE<br />
call cleanup(1)<br />
call _mode(0)<br />
File /etc/uucp/Devices must have entries (typically at the bottom) for<br />
/dev/cua/a and /dev/cua/b:<br />
ACU cua/b - Any hayes [not needed]<br />
Direct cua/b - Any direct<br />
#<br />
ACU cua/a - Any hayes<br />
Direct cua/a - Any direct<br />
The debug mode of cu also shows the missing entry from /etc/uucp/Dialers:<br />
# cu -d -l /dev/cua/a<br />
altconn called<br />
Device Type Direct wanted<br />
Trying device entry 'cua/a' from '/etc/uucp/Devices'. <== device exists<br />

call cleanup(1)<br />

File /etc/uucp/Dialers must have a "direct" entry. This is just the<br />
single, uncommented, word "direct" on a line by itself:<br />
micom "" "" \s\c NAME? \D\r\c GO<br />
direct <br />
<br />
I added following 2 lines in the end of ''/etc/uucp/Devices'' file:<br />
<br />
ACU cua/a - Any hayes<br />
Direct cua/a - Any direct</div>Boiarino
