Most of the mail I received was "tell-me-what-you-find-out" in nature; instead of individual responses, I'm just posting to the net. The bottom line (based on several informative replies) is that the Mac CANNOT (yet) be used as an X terminal over a serial line under the MacOS. One CAN use SLIP and MacX under A/UX, however. The most knowledgeable folks responding to me were hoping that Apple was working on SLIP for the Communications Toolbox under the MacOS. It seems obvious by the volume of mail that I got that this would be a Good Thing. Thanks to all who helped. Mark -- Mark S. Johnson mjohnson@stn9.me.calpoly.edu (129.65.19.9)

One CAN use SLIP and MacX under A/UX, however. Actually, it is possible. I'm using a SLFP developed here at the University of Michigan (its buggy, though, and I can't redistribute it, sorry) with MacTCP and MacX to dial in to my office's Unix machines over my 9600 modem. Works fine, usually, unless the SLFP hits one of its bugs (such as buffer overflow, I believe). Quite SLOW though. Running an X-Windows application using Motif widgets usually takes over 5 seconds to recognize a mouse click, for example. Works with System 6.0.5 and System 7.0fc2. It would be great if Apple would develop a good SLFP driver, I agree. -- Robert_John_Churchill@um.cc.umich.edu

Does the same as SLFP but is much faster. Also SLFP is mostly a local thing. One or two other places use it. PPP is on it way to becoming a standard for dialup IP, and an RFC has been issued for it. I can't remember the number right now. --Allan

Hi Allan, Actually, I have a PPP driver from Mark D. I haven't had much luck on getting it to work, though. PPP probably will be the "preferred" future, over SLFP. All a matter of time (& number of bugs), I guess. -- Robert_John_Churchill@um.cc.umich.edu University of Michigan ITD Consulting & Support Services Mac/Dos/Unix Consultant III, Programmer, and undergraduate PC2 archivist - mac.archive.umich.edu (141.211.168.70)

But I just have a simple related observation and question.... I can get MacX running past a GatorBox no problem. What I cannot yet do is get MacX going through the same network when accessing it through Liaison. I can telnet, tn3270, ftp, and read news fine, but I can't MacX.... I am a bit puzzled why I can't make this go, as Liaison ought to make a reasonably transparent network connection. (I guess my question is sort of about MacX over a serial line and sort of about MacX over a network connection.) Has anyone gotten this to work? If it shouldn't work, can anyone offer a GOOD explanation for why? Does it have something to do with some evil inside of the CTB? Is it just some sort of timing problem (I have V.32/V.42bis modems -- reasonably fast)? Just curious, and hoping for some insight.... If this has already been explained, I would welcome a copy via e-mail.... Thanks much in advance.... +---- C o n r a d C .
