Re: HP48 & Modems Message #2 Posted by Walt Devaney on 12 Mar 1999, 5:30 p.m., in response to message #1 by Marwan Joury
Yes, I experimented a few years ago with a combination of an HP-48 and both an Infotel 2400 Baud battery powered modem and later a ZOOM pocket modem. The application was downloading a small amount of data from a base computer. I never managed to get a usable system. The modems (at least the ZOOM) were smart enough to establish and maintain connections on their own, no problem there. But I never could get a decent communication program for the HP-48. Another problem was speed, 2400 Baud was the fastest the HP-48 could accept or send character strings. I have no information on what happens if you try to transfer binary files through the modem using any of the file transfer protocols. I doubt it would work. Another problem is that the PCMCIA modem cards have made these external modems hard to find. I assume you know you will need the communications pack for the 48 If you want any details, contact me through e-mail.
