# Code Table

Here is a table which will be useful for those who are doing their own RTTY programing. As you know ASCIl is a standard code for the exchange of information. Baudot is an earlier incompatible standard. The ZX81 and T/S1000 use a completely non-standard coding (the T/S1500 uses the same coding as the T/S1000). Here is a discussion of the contents of the columns in the following table which contains ASCIl, Baudot, and Timex/Sinclair information.
