Alistair,
Thanks alot for your examples. I still have one unanswered question...
How would you read a tuple of values (24, GID, Seq) like in my Erlang example, where 24 is one byte, GID is a 4-byte integer and Seq is a 2- byte word? Is there an elegant way of specifying packet format and reading/writing Haskell data according to it?
If you don't actually need a binary format (or don't care about the format) you can use the 'Show' and 'Read' classes to turn values into strings and back again. so, you would do a show on one side and send the string, and then on the other side 'read' it and you will get the same value out. Instances exist for all built in types where it makes sense, and you can automatically derive instances for your own types. John -- John Meacham - ⑆repetae.net⑆john⑈
