Hi,

 

I've have a Delphi 7 GSM modem application written by a freelancer, which i am 
thinking of porting to Lazarus/Linux, which means all components will need to 
be ported to Lazarus as well.  The app uses WSC4D (wsc32.dll - 

http://www.marshallsoft.com/wsc4d.htm

) from Marshallsoft which only works on Win32, so i will need to get that 
replace.  I searched the web and found Synaser and Synapse which supports FPC, 
so I am trying to figure out if Synaser is a good replacement for WSC4D, after 
which I intend to hire someone to do the porting work.

 

Some questions which came to my mind which I hope someone can help answer:

 

1. I read that Synapse uses synchronous sockets or with limited non-blocking 
mode.  What does this imply and will it affect my application if I use Synapse? 
 Based on my understanding, serial uses asynchronous communication.

 

2. I experimented with the demo and found out that it does not lock port, 
unlike WSC4D.  I also read that Synaser can lock port under Linux, but nowhere 
in the code or documentation does it says that Synaser can lock port under 
Windows.  My question is - can Synaser lock a COM port under Windows?

 

3. Will Synaser be able to replace WSC4D?  

 

Thanks.  Will appreciate any comment.

 

Rgds,

Joshua
