I have investigated, and found the following bug. VLT (v. 4.846) will crash
if you attempt to send a break to your Supre 2400zi. This is independent of
the processor you use (68000 or 68030), and does not occur if you use the
serial.device. Thus, I am leaning toward the possibility that the bug lies
in modem0.device, but I guess this hasn't been proved. Does Supra have a
net.presence? This bug is probably causing the problems that I reported
eariler between getty/VLT/modem0.device. I am still looking for answers.

I believe it assumed you reset the io_Length field to 0 or some such.. Also when I used modem0.device, there was a net memory loss of 24 bytes. Not really worth worrying about, but both sloppy programming mistakes.. -- +---------------------------------------+----------------------------+ | // Daryl S.

I am still looking for answers. At least one related problem exists in modem0.device - if it is asked to open in shared mode twice, with different settings the second time, it will crash immediately. Found this when I happened to run TrapDoor on top of uucico. Could even be the same bug... -Henrik | Henrik Clausen, Graffiti Data | | ...{pyramid|rutgers}!cbmvax!cbmehq!adspdk!hclausen | \__"Do not accept the heart that is the slave to reason" - Qawwali trad__/

This bug is probably causing the problems that I reported >eariler between getty/VLT/modem0.device. I am still looking for answers. modem0.device may have yet another problem. Using Whap! V1.9C (the CIS automated telecomm program) I cannot upload files without incurring hundreds of read errors. Downloading is no problem. I am using the current release of modem0.device, but the problem seems to be apparent on earlier version of the driver. Of course, I don't know if it is the driver - just guessing at this point. -- /\ /\ //\\//\\ +---------^^^^------------------^^^^---------+ | From the shack of WA1OMM -- Paul MacDonald | | Using the power of the multitasking Amiga! | | | | Compuserve: 70411,626 PLink: UPPERCRUST | | Amateur Packet Radio: WA1OMM@KB4N.NH.USA | | Usenet: ...virgin!ubbs-nh!wa1omm!paul | +--------------------------------------------+ /\ / /\ (~ / / / / /\ /\ / / / / V /~~\ _) /~/ /_/ /~~\ , / V /~/
