[comp.sys.tandy] Tandy 1400HD Question

gklimes@gmuvax2.gmu.edu (George Klimes) (02/06/91)

My girlfriend has a Tandy 1400HD. She has an external 2400 bps modem
and a serial mouse (an external modem is much cheaper than Tandy's
internal card). Right now, she has to swap devices whenever she wants
to use the one not attached. I recommended a serial switch box (A/B box).

Question: Can a MANUAL one be safely used with the 1400HD, or will she
have to purchase an AUTOMATIC one (which she won't probably do because
of the cost)?

Why waste the money on an automatic? All it takes is a flip of a switch with
a manual serial a/b box. To me a more important point: She can ave RAM
and annoying error messages upon bootup if she puts the mouse.sys
file, etc., in a batch file, to be executed only when she wants to
"mouse around." Free up 20-30k.

BTW: I've been thinking about loading my command.com into a ram disk
in that extra 128k of memory -- again free up some RAM, cut down on
hard drive i/o, etc. I saw some statements to be put into an autoexec,
or maybe config.sys, once upon a time, that would move command.com into
a ram disk. Anybody out there know what statements to put where?

Howdy. I have similar problems with Tandy 1400 too. Modem/Mouse and null
modem connection. I am thinking of the manual switching box too. I doubt
it will cause any problems, since I have been plugging and unplugging the
RS-232 connector while the machine is on. Nothing happens (so far :)
