That really depends on the BASIC source code and the compiler used... There
are some compilers that are pretty bare bones and can make pretty clean M/L
(Loadstar has a tiny BASIC one that does integer BASIC compilation only - no
runtime, straight M/L but a limited command set. AustroSpeed/Blitz programs
can get smaller if the source is large, but that is P-Code and not as efficient.
I've heard good things about Abacus' BASIC 64 and 128 compilers in that they
can either do pcode or straight ML, but havent used them myself.
PETSpeed is an optimising compiler, but it is very cumbersome by even 64
compiler standards and I don't think it was much better then Austrospeed/Blitz.

You can get the 64 Programmer's Reference de from the Project 64 archive at:
http://ourworld.compuserve.com/homepages/pcgeek/proj64.htm
which will supply you with the BASIC code necessary to connet at the proper
speed, but you mau also need to covert PETASCII<>ASCII too.
300 baud is not all too fast for even uncompiled BASIC; what sort of response
time is he looking at?
