SunOS has the old BSD 4.2 version of talk. The old talk uses “machine dependent” byte ordering. Since DEC has different byte order the two talks can not communicate(even if you use “otalk” on the DEC machines). Also, most vendors have the newer version of talk from BSD-4.3 and this version is not compatible with the Sun Version(which is BSD-4.2). The solution is to get and install the new version of talk because it uses “network” byte ordering and it is compatible with most Vendors current talk implementations. “New Talk” is available via anonymous ftp from several sites including thor.ece.uc.edu(Get the file /pub/sun-faq/ntalk.tar.Z).
