I have been trying to run QMODEM under Desqview for a few weeks, and although it runs fine for a while it has a tendency to crash the system, or cause strange things to happen. I started to use QMODEM as a replacement for PROCOMM Plus, because I found that under Desqview, at 9600 bps, PC Plus would lose characters. The system I am using is an IBM PS/2 Model 60 (286). It seems that this character loss problem is particular to the PS/2, I think because of the way the interrupts work. The solution was to find a comm program which would use the 16550 UART in the PS/2 serial channel. Apparently, PC Plus cannot do this (though I have heard some recent, unconfirmed rumours that maybe there is a new version that solves this problem). QMODEM offers this capability, and character loss dissappears. However, the problems are as follows: - The machine will sometimes re-boot when pressing a key other than Ctl-Alt-Del. - The font sometimes changes, to one which underlines all characters which have decenders. - Colours sometimes change. - Cursor control is sometimes lost (i.e.. the arrow keys), though everything else seems to work. This happens when running WordPerfect as the second program, and QMODEM in the background. - QMODEM sometimes fails to execute at all on an open window command, hanging the machine in the process. If anyone has any comments, solutions etc, I would be pleased to hear. I am running QMODEM 4.1, by the way, and the available memory includes an Intel Aboveboard (LIMS 4.0).
