    First off choose "USR HST/HST Dual (9600-28800)" for 'modem', assuming
your using ProTERM 3.1 with the latest file version of 'PT3.CODE0'. On my
IIgs I use the default init string it supplies, although I added '&C1' and
changed '&A0' to '&A3'. The complete initialization string is then:

ATX4&A3&B1&N0&H1&I0&R2&C1

    You must have an properly wired hardware handshaking modem, but if not
try using this initialization string instead (for software handshaking). 
I used it on my IIgs before I had a HWHS cable, and currently use it to
get my USR modem to work with my Apple IIc Plus.

AT&FX4&H2&B1&I2&K3&M4S38=254

    It will certainly work best on the Apple IIgs, since (even stock) it 
has decent serial ports and enough speed to handle a 14.4K modem, which
really isn't the case on an Apple IIe. 

    Incidentally, what year is marked underneath your Sportster modem?
I have one from 1992 which works absolutely fine with my IIgs using a
hardware handshaking cable _and_ regular cable (using software hand-
shaking) but had nothing but trouble with two 1995 Sportster modems.
I ended up returning both those more recent modems, and instead waited
for my brother to upgrade to a 33.6K Sportster so he could pass on his
older modem to me.
