41C on packet radio?

[Garth Wilson]

How big are the packets? I've never really looked into packet radio; but I assume that what you're considering a potential problem is the receive-buffer size. The 41 can supposedly do 150 bytes per second on HP-IL, about 3% as fast as the 71 can. Actually doing something with those bytes might be another matter.

I have the FSI164A rather than the HP82164A. It seems to be pretty rare. They two are mostly compatible, but there are some minor pros and cons to each. One advantage to the FSI unit is that the default receive-buffer size is 1024 bytes, and the manual says the max size is about 10 times as big as that of the HP unit's. With a quick scan, it has been difficult to tell if the 1024-byte default size is the max or not. (It also says you can extend the max by adding memory inside.) What is the max size of the HP unit's receive buffer?

Regarding the requirement for the Extended I/O module, I don't remember ever having to use the HP-IL commands manually. I think I've always just used the REMOTE commands. I have the XIO built into the HP-IL module, so together the two only take one port. I bought them that way, brand new, from EduCALC; and since they're together, I tend to forget which module certain instructions are in. As I look in the XIO manual now, I do see that the REMOTE, LOCAL, and NOTREM commands are in the XIO.
