RTS Control TSR v1.2
Copyright 1994 Michal Szokolo
FREEWARE
1. License
RTS Control TSR is provided 'as is' and is not subject to any warranty
of any kind. You use it on your own risk.
You may distribute RTS Control TSR in any way, except including it as a
part of a package sold for profit.
2. Idea
At the time comms program writes received data to disk, it's not able to
service incoming characters from modem. This creates situation, where
some characters may get lost. Good comms programs do lower RTS signal
while writing, to avoid this (low state of RTS tells modem not to send).
However, disk caching software featuring backround/staged/late writes or
whatever they call it, differ moment of application completing write
request from physical write to disk. So, it's probable that real writing
occurs when comms program is unaware of that, resulting in losing one or
more characters, which leads to CRC error and retransmission of data
block. This makes transfer longer, thus increasing cost.
RTS Control TSR monitors disk access at BIOS level and can lower RTS
when disk operation is carried on. The effect is especially visible when
using slow disk and/or inferior caching system, like SMARTDRV.
3. Usage
To install RTS Control TSR it must be run with a port number as a
parameter, eg:
RTS 2
RTS Control TSR will monitor COM2: (under standard address).
RTS Control TSR has no provision to unload or service more than one
port. This may be possible with some future version.
PLEASE NOTE: RTS Control TSR must be loaded BEFORE disk cache but after
any speed boosters (like IDEBOOST).
4. Other...
Author is asking you for constructive remarks about this program.
