Sorry for the delay in replying. Most universal remotes don't support the Infocus or ASK projectors. Some OneForAll remotes do, but are no longer in production. Here's a list.  Perhaps you can find these used. Use setup code TV 1164.

URC-7555
URC-7556
URC-7940
URC-7950
URC-8350
URC-8203 (using setup code TV 0781)
URC-8305
URC-8308
URC-9040

Many functions defined by ASK aren't supported by the remotes as supplied from the factory. So you'll need to assign 5 digit EFCs to buttons.

First assign setup code 1164:
1) Tap TV
2) Press Setup (or Magic or Set) until the remote blinks twice.
3) Enter 1164

Nex, assign an EFC. For example to assign Overscan to Ch+, look in the table below and find that the corresponding EFC is 00152.
1) Tap TV
2) Press Setup (or Magic or Set) until the remote blinks twice.
3) Enter 994 (the remote should blink twice)
4) Tap Setup
5) Enter 00152
6) Tap Ch+
The remote should blink twice.

Now pressing Ch+ should cause the projector to perfoem the Overscan function.
