| Y-Modem |
Y-modem is a file transfer protocol very
similar to X-modem but usually transfers data in much larger blocks of 1
kilobyte - if the lines aren't noisy, this works well - most implementations
allow negotiation with the other computer to see if it can handle the larger
block size; if not, the 128-byte block is used |
| both X and Y-modem protocols have problems
when things get out of synchronization, which usually leads to Bad Things
happening - and the checksums aren't particularly robust, so that lead to
Z-modem |

Yet Another Compiler Compiler - a Unix
