Various vendors (like HP :->) provide RJE and SNA offerings for some of their systems; give your vendor a call and find out. Andy Valencia

? From: Guy Harris <guy@gorodish.sun.com> ? Depends on what you mean by "special conversion hardware". I don't know what ? electrical standards (such as RS-232) are used to connect to bisync modems, but ? if you can use RS-232 for that you don't need any special conversion hardware. ? (There are probably lots of issues about "who supplies the clock" for the ? modem.) BISYNC is a protocol that runs in synchronous mode. There are several USARTS that do async, sync, and [SH]DLC, all over the same line. I believe it's the DCE that supplies both clocks. I believe the dmf-32 has a sync mode as well. Now as for the protocol, have fun! I believe it's been done before. Hey, if you can do SLIP...

The is no requirement made by the frame level protocol on the electrical level interface. Thus BISYNC can run on RS-232, RS423, RS-422, RS485, MIL-188c MIL188-114 or any other electrical interface. I have even seen BISYNC run over ETHERNET. The point being made is that with so many options the buyer should beware. Glen Warholic gaw%columbia-pdn@acc-sb-unix
