Provides a serial port and synchronous TCP/IP Library.
Unit cryptlib and the SSL part of Synapse require the cryptlib library. If library is not present on system an error message appears during linking:
/usr/bin/ld: cannot find -lcl
Note: it may very well be possible to use OpenSSL libraries for the SSL part of Synapse. You will also need a library and the openssl_* units from synapse.
